This is a mini-review to go with our series on tunnel tents. It reviews the Macpac Olympus. Some of the illustrations are from the manufacturer's web site and from friends, used here with acknowledgement.

Introduction

Tunnel Tents Tutorial and State of the Market Report: Macpac Olympus Review - 1

The Macpac Olympus is a world-class tunnel tent designed to handle some of the harshest conditions in the world: the New Zealand Alps in winter. The Maori name for New Zealand is 'The Land of the Long White Cloud;' the rest of us often call it 'The Land of the Long Black Never-Disappearing Cloud.' I make no apologies for this tent. First, the specifications. Please note that they are for the current model of the Olympus, but I used to have the older version.

Brand Macpac
Model Olympus
Poles 3, DAC Featherlite NSL 9.6 mm
Skins 2
Fly Fabric "UV30TMSI / TorrentwearTM XP"

Details

This is a double-skin tunnel designed for very serious winter use, but usable all year round. I better point out that I owned an earlier model of the Olympus for many years, and found it lived up to its reputation in every way, so I may sound a little biased. I have also found that the distinctive shape gets recognized even in Europe - with respect. The sunny photos were, as usual, taken at my place - much warmer than in the snow!

The poles supplied with the tent are DAC Featherlite NSL. They are colour-coded so you know which pole goes where in a howling storm. However, at my urging, Easton supplied me with a matching pole set using their Carbon FX tubing and their alloy elbows. These poles weighed 395 g (13.9 oz), somewhat lighter, but very strong. At the time of writing, I understand Macpac was in discussion with Easton about this option. Both sorts of poles have those silly knobs on the pole feet, but the knobs are fairly small and the eyelets are rather large. I doubt the knobs will be a problem.

The Torrentwear XP fabric used on the bathtub groundsheet is a PU-coated nylon with a hydrostatic head of 10 metres - that's a lot. The seams are tape-sealed. This, and the name, reflects the nature of the ground frequently encountered in New Zealand. (This is not a criticism of NZ: they will tell you this themselves.) I cheat slightly here in trying to illustrate this: the Minaret tent shown here is the smaller two-pole twin to the Olympus. Photo by Marty Schmidt, NZ Guide, East Ridge, Mount Cook.

The UV30 fabric used for the fly is double-coated 30-denier double rip-stop nylon, basically a form of silnylon. At 60 gsm it is heavier than the common Westmark silnylon, but it still seems very light. As the name implies, the silicone polymer provides some UV resistance, and of course increases the fabric strength. It is rated to 3.5 metres hydrostatic head, which is very good compared to many silnylons.

While the tent does allow access from both ends, plan on only using the front end where there is a decent-sized vestibule. The rear end-bell shown here is largely occupied by the rear end of the groundsheet, providing access, but no vestibule space. This is a change from the earlier model, which was symmetrical in design. We used to stow our packs at the rear end. Doing so left the front vestibule clear for cooking and so on, but the vestibule was smaller. Frankly, I think the only use for the rear 'access' will be ventilation in fine weather, and maybe an emergency exit for the second person while the first is up front cooking.

Tunnel Tents Tutorial and State of the Market Report: Macpac Olympus Review - 4
At the rear end there is good provision for ventilation, even when the weather is foul and the main door is closed. There are some small vents protected by mesh that can be left open or sealed right up. Full mesh doors at both ends as well as the standard fabric doors protect you from the deadly New Zealand sand flies while you sleep, with a good amount of through-ventilation. (Sand flies are very similar to Scottish midges; both are nasty.) Note however that the zipper on the inner door does go around a corner at the bottom: you need to exercise a little care here.

Owing to the design of the bathtub floor and the interior tent, it is possible to unclip the front end of the ground sheet to roll it back a bit to make an even larger vestibule space. This can be very helpful when the weather is filthy and you need sheltered space to strip off storm gear. It also makes for a very large cooking area - larger in fact than one would normally need.

The inner tent is a very light white fabric. It isn't quite see-through, but it certainly does not block incoming light. It does block most of the wind though. I can't help it that under benign conditions it looks a bit like the inside of a harem... The inner tent has huge pockets on both sides for light gear you don't want lost (or squashed) on the floor. The inner doors (rear one shown) can be held out of the way by small elastic toggles. These were a bit tight on the tent supplied, but Macpac took note of my comment and said they would fix that. There's a bit of room at the sides for gear, keeping your quilt off the sidewalls too.

Snow Loading

Tunnel Tents Tutorial and State of the Market Report: Macpac Olympus Review - 6
These two photos are before and after ones, taken in the Australian Alps by Jon Legg, Macpac staff, Adelaide. While some types of tents tend to collapse a bit under snow loading, a good tunnel tent does not. Incidentally, I have numerous similar photos of the older model Olympus in similar situations. You might like to note the small dark areas at the end of the tent: the vents are still open and functioning. This ability to handle high winds and snow loading is one of the key features of any good tunnel.

Pole Sleeves

The Olympus has the pole sleeve inside the fly rather than outside - it has always been that way. The distinctive shape of the tent helps to locate the poles exactly where they should be, and I can attest that this works very well. You can only insert the poles from one side - they go into a webbing socket at the other end. The pole feet have little knobs but the eyelet on the insertion side is large enough. Sleeve tightening is achieved using webbing. The tent that I owned used Easton poles, but, as noted, Macpac has since switched to DAC poles.

Stakes

This is a tent designed to handle very serious conditions. Macpac supplies four large tube stakes for the ends and 12 special Macpac-design channel stakes, and a very light silnylon bag. They should hold under any summer conditions, but are not usually good enough for the snow. A common end-bell anchor for snow conditions with this tent is often a couple of ice axes, although two deadman anchors are fine.

Summary

Tunnel Tents Tutorial and State of the Market Report: Macpac Olympus Review - 7

Yes, lots of hype, lots of claims, not the lightest tent on the market, and expensive. That does not stop an awful lot of people in our neck of the woods from buying this tent and using it hard. It was born for use in this sort of country and is regarded by many as a gold standard for tunnels.

Warmlite 2R front upper vent on 04/24/2012 16:15:52 MDT Print View

Loads of super-interesting info to digest! This is really fun. For the moment, just a comment on that weird front upper vent in the 2R:

> in bad weather you won't get much ventilation

The design is unusual but it works, maybe not any better than the most typical hood covered vent but it works. The hood is actually there but inside the main, mesh covered wall instead of outside of it. It can be left open in bad weather unless the wind blows horizontal rain/whatever in.

It takes some inside room but the exterior is more streamlined and the hood needs no stiffener.

Mini review not as thorough as your usual reviews -- but I guess that's why it's called "mini" on 04/24/2012 17:59:36 MDT Print View

You didn't show the versatility/variety of ways the front vestibule can be configured. Shame on you :)

Not up to your usual methodical high standard (eg. you mention the Nallo 2 can be double-poled, neglect to mention that the First arrow can too, neglect to consider that the velcro attachment of inner to outer for the Olympus is fiddly at best -- far easier to separate and reattach the inner in the First Arrow, so for me the value of the mini reviews is limited).

Point being, these mini reviews are just that and I'm not sure that they particularly give much information beyond what a little experience and erecting the tent in a shop and looking at it would yield which is a little disappointing (not everyone gets access to tents they can play with in the field).

That said, I did learn a few things (including on tents I am unlikely to have the chance to play with like the Stephenson) so appreciate your review.

I know Vango don't market the Tempest as 4 season, but wonder whether you can speculate why it is less robust than other 2 pole tunnels like the Nallo (yes the fabric will have a lower tear strength... who cares to a degree... and the poles are probably not quite as high quality but do you have a feel for whether this is significant for the majority of conditions likely to be encoutnered)?

Disclaimer: I do not recommend the use of this tent for 4 seasons just as Vango do not market it as such. Just curious as to where you think corners have been cut that really would impact performance in wind and snow.

Cheers
Stuart

Hi Stuart

Yes, these are just MINI-reviews, to go with the Survey & Tutorial. They are as much examples or illustration as anything else. I was hoping the pictures of each tent would give a bit more info, beyond the basic specs.

Double-poling. Frankly, I suspect this is another one of those great ideas which never get used in practice. My winter tent was fine with single 7 mm CF poles in that storm.

Velcro attachment fiddly: yes, but I think one would have to be nuts to even contemplate ever separating the inner from the outer on any light-weight tent. There is just no point. The only time I might do it would be to wash the inner tent!

Vango Tempest 200 - can it be used 4-season? Well ... it is not a bad tent, despite the very low price. I think it is aimed more at wet weather with wind than serious high-altitude snow - and at DoE kids. Just how well it would survive a serious snow storm might depend rather a lot on the skill of the person in finding a site with a little protection and in pitching the tent. You would not expect DoE kids to be camping on top of the Ben for instance.

Cheers

Re: Warmlite 2R front upper vent on 04/25/2012 04:25:03 MDT Print View

Yeah, I pretty much agree with the front upper vent not working that well. I have used the Stephensons in some really wet conditions in the NE part of the USA (including one ten day trip that rained solidly for 3 days and every day we were out paddling.) The vent itself is simply too small and is the ONLY high vent in the entire tent. I believe it needs more, high ventilation to provide a proper chimney effect. So, except in winds greater than 30mph, it really doesn't work that well. Most of the time, we easily find some sort of wind shelter, often a grove of trees, a larger rock or bushes, to hide the tent from major winds. I have asked the wife to put a second vent in below the first. The style seems good. We *did* have a minor leak at the base of the vent (the bottom of the "V".) I seam sealed it again and it went away. This was the only downside to the vent design.

The tension does not appear to be a problem. In fact, it seems to accur as a product of the angle to the ground. So, the three basic stakes are enough to do the job. In higher winds, four others are needed, at each hoop end, of course. I also use 16" guy lines on the window awnings leaving about a bit of vent clearence on the bottom. These also supply additional stake points for the canopy leaving a total of 11 staking(pegging) points on the tent. It does NOT move.

Roger,
Exped dropped the Aries tent from their offerings this year.
The Sirius has been gone for a while, 2006 or so? But, this included a light, fabric inner tent. Good in windy conditions. The vents are all zippered to allow adjustment of the outer vent hood from the inside. Overly elaborate....

Separating inner and outer on 04/25/2012 06:17:05 MDT Print View

I think I have occasionally done it for drying. Never for load sharing.

For temporarily enlarging the vestibule I think it can be useful (the attacjment on the WE tents is very quick and easy and I think from memory vango may use a similar system). Also to take the outer alone, which I did once and have learnt my lesson (trip turned into a sand pit, with plenty of rain and even mosquitoes one night (the last two not expected at all as advised by park rangers pre trip)... probably never again.

Also if the weather was particularly not very nice (edited due to possible profanity) to be able to pack up dry. I'm not sure I've ever had to resort to that though.

Taking fly only allowed me to take a nice heavy camera however, so once the memory of that trip fades, maybe I'll give it another go...


I guess one liveability thing against the Vango in winter is the vents which can't be closed.

Incidentally, the bracing Vango (so called TBS) uses on the poles - they specifically do not claim this increases wind resistance (though it obviously should increase stability in cross winds, i.e. liveability but this is not to be confused with an increase in the upper performance limit of the tent in a crosswind I think - in fact I would not be surprised if it actually reduces it by concentrating forces). Anyway, I'm interested in the concept. With luck maybe such a system will appear in the wind testing project BPL is doing for lightweight tents.

A bit of a let down on 04/25/2012 11:01:18 MDT Print View

The qualities of the reviews aren't the let down, the product on the market is. I have skimmed the mini reviews and looked at the comparison table. I can't decide if it is writer’s bias or truly lame designs available on the market. All of the tunnel tents on here don't seem to hold a candle to the Caffin designs... Either you pay a large weight penalty for high quality or you pay a size or quality penalty for weight.

Except of course when you look at the two Caffin tents that have seen years of service, are still going strong, and are substantially lighter than anything else available.

What do I do now, I had decided about a year ago that a tunnel tent was in my future for strong conditioned winter climbing but none on the market seem to be reasonable.

I may just have to look into making one.

How much effort and sewing skill go into making the Caffin Winter Special?

How much math and physics are in the design?

What are the approximate material needs for the Caffin Winter tent?

So Roger if you don't secure a manufacturing contract in the next so long say 6 months could we expect you to be selling patterns and instructions on making your own ? Or maybe a kit for making your own?

Hi Jeremy and Peter

> selling patterns and instructions on making your own ? Or maybe a kit for making your own?
If the commercial deal does not go through I will be again helping people MYOG. But bear in mind that the 'instructions' are NOT a hand-hold job! They are MY guide, so much study is required.

> How much effort and sewing skill go into making the Caffin Winter Special?
A lot of effort. Yes, it is a long project. Sewing skills required are medium: it is just about all straight stitches. Much study of the plans and instructions needed. Careful pinning up and sewing is what makes it. Some tools required.

> How much math and physics are in the design?
The design is totally mathematical. It is based on parameters like height, width and lengths of sections, pole curvature, tilt angle ... Its a full 3D parametric model.
There is some physics as well, but more concealed in the design and model. Pole curvature for instance: limited to 1800 mm to avoid breakage, fabric stretch (a %) for tension, etc.
What comes out are the fabric patterns.

> What are the approximate material needs for the Caffin Winter tent?
Um ... roughly 8 m of silnylon and 4 m DWR fabric, plus netting and arrow shafts for poles, and string. Zippers are #3 coil. Some 20 mm hook&loop tape. Eyelets of 2 sizes. Also elbows - the difficult bit as they need a lathe, and pole feet.

Rest assured - I will update the status when I can.

Cheers

That may be a little unfair to the commercial tents. Some of them are good, even in extreme weather.
The problems you are seeing come in several places:

* Range of customer requirements: not everyone is stupid enough to camp on a snow-covered saddle in a 100 kph storm. Many people genuinely need something a little lower in performance.

* Cost of manufacture: always higher for this sort of tent, even via China. The high quality tent has to be able to sell in competition with cheaper tents. And the manufacturer usually cannot afford to make a really wide range to cover every eventuality. He has to compromise a bit.

* Range of customer experience: let's face it: commercial products get bought by people of various skill levels. A mass-market tent has to be able to handle some misuse by novices in the field. The expert user pays for it.

* Retail resistance: unless you sell via the web, you have to placate the retailers as well. They don't like things which take a lot of explaining, and they really don't like things which novices break and return. This is a generic problem for the whole UL sector - which is why the cottagers sell via the web. Roll on web sales!

Yes, my tents are ultra-light, and yes they provide extreme performance, but they could be trashed by novice mistreatment. They have lasted so long because I care for them.

But maybe you have unfairly condemned the commercial tents anyhow. The Macpac Olympus is widely regarded as legendary in this part of the world. The other European tents are designed for European weather - which can be bad. You do have to pick the right model though - a Hilleberg pop-up is still a pop-up, even if well-made. The American tents seem less favoured: both suffer from design faults and one of them has very poor manufacturing quailty in my humble opinion. YMMV.

Roger, I'm curious why you decided to review the Vango Tempest 200, which is clearly not in the same class as the other tents, as one of your worst weather scenario tents, rather than the Vango Nitro Lite 200, which was specifically designed for the same conditions as the other tents, and is significantly lighter and made of better materials?

"Zippers are #3 coil"

I've been experimenting with #3 coil zippers. I haven't totally decided if they're strong enough. I like the reduced weight compared to #5.

Do you put tension across the zipper, like when you have your 100 kph winds?

Do you think a #3 coil zipper might fail?

Do you use regular YKK zippers?

Ah, yes, I agree that the Nitro Lite is nice. But all the head office had in stock was the Tempest 200 - and I had to wait a while for that. Seems they build some of them to retail order maybe?

PS: don't knock it too much: the Tempest 200 would be a good reliable inexpensive tent for some adventurous kids.

Re: Re: A bit of a let down on 04/25/2012 19:05:59 MDT Print View

Hi Jerry and all

OK, getting technical now.

I have never had a #3 coil zip fail in the field, and they have had a 'fair bit of use'. No problems at all - in my hands.

So why do manufacturers use #8 and #10 zips? In a word: novices. Or perhaps more accurately, careless teenage males. Every manufacturer I have spoken to about this problem has virtually cried on my shoulder about the way some kids trash their gear - and then expect free repairs. Many of them agree that #3 has quite enough strength, but they dare not.

Under storm conditions the zips at the rear end of my tents do have a lot of tension along the tape but not too much across the zipper teeth. In fact, I actually use the strength of the nylon zipper tape as part of the design. When you look at the fabric tension distributed across a zip in most situations, it is not that high.

Caution: do not use a zipper slider to pull the two sides of a zip together. that way will trash both the teeth and the slider. Bring the two sides together by hand first, then run the slider up the length.

Do I use 'regular YKK zippers'? Not sure what you mean here. I use YKK, RiRi and a few other brands available locally, and truthfully I have not seen much difference between them. The zips on my tent are not YKK: they are off a large roll of continuous-chain coil-coil #3 zip. I do use solid metal sliders.

Comment: I see some manufacturers boasting about how they use 'only YKK'. I suspect they are being given a discount for saying this. The YKK brand is not very different from the others as far as I can see, but they have great marketing.

The description of the Vango Nitro Lite 200 looks good. I don't think Vango exports to the US. Too bad, it looks like it would be a good choice for a light, one-man tent for winter and bad-weather use...

Thanks for the comments about zippers, Roger, that makes sense, that's the direction I'm going - #3 coil zippers on everything and try to be a little careful

"Caution: do not use a zipper slider to pull the two sides of a zip together"

I know what you mean. When I cinch down the corner guys on my tent because it's windy, it tends to pull apart the zipper. If I unzip it, and zip it back up I have to be careful.

Hi Jerry

> When I cinch down the corner guys on my tent ... it tends to pull apart the zipper.
I know exactly what you mean. After much thought and experiment, I eventually took the bold step of locking the bottom end of the door zips together. My doors no longer open upwards, only downwards. I step over the crumpled-up door to get in and out. Problem solved - and the corner of the tent is stronger for it.

You might ask whether this causes problems with ventilation. No, it does not. At the rear end of the summer tent there is an inlet air gap at ground level. At the downwind end I want the exit vent to be right up at the roof. So opening the door downwards is correct. Yes, that does mean I have to have a good hood over the top of the door to keep the rain out. The hood used has always worked very well.

For the winter tent I have a sod cloth at ground level at the rear end which can be tucked out of the way if not needed, and an inlet vent at the top of the 'door'. In fine weather I tuck the sod cloth out of the way. In bad weather ... I shut most everything because the tent is usually pumping quite enough for ventilation anyhow. :-)

Carbon fibre poles on 04/26/2012 00:32:18 MDT Print View

Dear Roger,

Very good reviews.

I have a Nallo 2 and I am wondering about replacing the metal poles with carbon fibre.
I can source the poles through Fibraplex. I haven't looked into your arrow shafts yet. I assume any information about using arrow shafts is on the Bushwalking FAQ site.

My worry is would the carbon fibre pole need the elbows as you have with your tents? Fibraplex stock elbows but they have a relacement kit for the Nallo that doesn't include elbows.

What do you think? Would the arc be too great without elbows?

Regards,

Gordon Bedford

Re: Carbon fibre poles on 04/26/2012 01:45:18 MDT Print View

Hi Gordon

I hauled the Nallo 2 poles out and had a look at them. Yes, they have a pre-bend. Not large, but it is there.

My gut feeling is that you would be pushing the CF poles too hard withoput elbows. They might survive on the back lawn, but once the tent moves a bit in the wind in the mountains ... bang.

What about adding a (say) 10 degree elbow between each pole section? Maybe ... The pole sleeves tend to be a bit more forgiving than an embedded sleeve in handling corners. I would NOT go for just 2 -3 big elbows with a tent designed for a smooth curve: you will need to distribute the bend along the length. yes, I have tried that already with the Olympus and some Easton CF poles.

Suggestion: Take a few measurements of the Al pole on the ground with the legs at the right separation, and then use a graphics pkg to see what a CF pole with elbows would look like over that profile. Failing a graphics pkg, use a very large bit of butchers paper on the floor. Make up a cardboard edge with a radius of curvature of (say) 2000 mm to represent a CF pole, and see how it all goes.

I use a radius of 1800 mm for the formal design work. That has worked OK.

carbon fibre poles and separating the inner on 04/26/2012 05:05:06 MDT Print View

Thanks very much for your advice Roger.

Having just read all the posts I noticed Stuart Murphy raised the issue of separating the inner from the outer. Now I know you disagree but I will throw my two bob,s worth in anyway.

It all comes down to what experiences one has been through and these are mine.
1. Day after day of wet weather means the inside of the tent eventually gets wet.
2. Wet evenings followed by cold still mornings means the condensation builds up on the closed up fly while you sleep.

In both of these situations keeping the inner dry is/has been my main aim and this is most easily achieved if the inner is packed up separately.

3. Sometimes in a big storm in the cold areas of the world we have just wanted to get out of the blizzard and take stock. you don't want to put the inner up.


If the the inside of the fly is dry I would always pack it up together but if it is wet then I separate. This is the great advantage of tents put up this way.

regards,
Gordon

Re: carbon fibre poles and separating the inner on 04/26/2012 16:06:55 MDT Print View

Hi Gordon

Understood.

My experience has been that the inner tent dries out a bit if it has a GOOD DWR in the period between pitching it and going to sleep. With the two of us active and eating in the evening, enough heat seems to be generated. Not perfect, but it helps.

The other advantage of keeping them together is the speed with which I can get Sue inside the tent. As soon as the two ends are pegged down, in she goes, while I do the guy ropes. By the time I am ready to get in, the vestibule is clear for me.

Re: Carbon fibre poles on 04/26/2012 18:41:58 MDT Print View

Gordon,

Note that Fibraplex make replacement poles for the Nallo 3 and 4, but NOT for the Nallo 2. I'd be pretty confident that is because the curvature of the Nallo 2 poles is more than the fibraplex poles can handle.

So if you use fibraplex pole sections to make a pole set for your Nallo 2 you will need some sort of elbow.

At most you might save ~200g or so (say 6 oz). I've thought about this on-and-off and so far have decided it isn't worth it for me. But if you have a go at making a carbon pole set, please keep us informed on BPL!

Cheers

re carbon fibre poles on 04/27/2012 01:00:47 MDT Print View

Roger,

Yes well to be honest I only separate if I consider the inner wet enough at pack up time.
I had a Fairydown tunnel tent 20 years ago which was great except it was so difficult to connect inner to outer you could nearly die in the time it took. I sold it after one trip.

Tuart,

I have been in contact with Fibraplex and they do have a Nallo 2 replacement set with bends as Roger suggested. I have added a third pole to my Nallo for the reasons of snow loading outlined by Roger. They have indicated I could replace this as well with one of their carbon bibre poles.

This whole review is great for improving the knowledge and quality of tents.

Gordon

Thanks Roger for a good review, "mini" though it was. I do like tunnel tents for their aerodynamics and even more for their roomy interior space.

I think the main reason MSR made the Dragontail tent a single wall was to cut down on weight. As for the new pole clip arrangement, I agree, for a WINTER tent the pole sleeves should be a "requirement" - tunnel or dome. Sleeves also spread out the stress on the fabric in extreme winds.

Even with my TT Moment 3 season tent I modified it to allow the "crossing pole" to go inside (then back out reinforced holes at each end) to more fully support the canopy in high winds or unexpectedly heavy snow.

Warmlite history on 04/30/2012 11:26:37 MDT Print View

Roger, you decribe the Warmilte 2R in your mini-review as "deriving from the mid-2000's". I think you're a little off on your history there. That tent dates back to the 1960's at least - with the only difference being the fabric, as Silnylon was not avaialble then. Stephenson's were possibly the first to use silnylon in their tents, and had been using urethane-coated 1.1 oz nylon before that. And by the way, you may find this site interesting, as it contains many tidbits of backpacking gear history:
http://www.oregonphotos.com/Backpacking-Revolution1.html

I'm in agreement with you on the design shortcomings of the Warmlite tents. No vestibule just doesn't cut it for me. And they admitted to me in a response to an email query that the vents cannot remain open in the rain and snow. But I am interested in the poles, and have been for a while. I see you have a weight for the set of poles. Did you weigh just the larger front pole separately? My interest lies in making a tent similar in size to their 3R, which uses the 2R front pole at both ends. And I take note of your comment on the fragility of the thin-walled poles Warmlite is using.

Re: Tunnel Tents Tutorial and State of the Market Report - Part 3: The Mini-Reviews on 04/30/2012 14:41:38 MDT Print View

Re: the lightwave tunnels, they've just released an interesting new 2 man model (the T2 Hyper) which has simultaneous or outer first pitch, unlike all their other models which are inner first only. No useful information about it yet, though, other than the fact that it seems size and cost comparable with the Nallo 2.

What's with the lack of 2-door tunnels in the market, though? HB have the Kaitum and Keron and Macpac has the slightly useless rear door on the Olympus, but the offerings beyond that seem nonexistent. I'd consider cost or weight or complexity to be an issue, but even competent tent manufacturers like Lightwave and Helsport don't seem to bother, despite their offerings including heavy, complex and expensive tents.

Another take on Australian weather... on 05/01/2012 20:17:25 MDT Print View

Another take on Australian weather.

Australia is the flattest, driest continent on the planet. There are relatively small areas above the treeline where, like other countries, the weather in winter brings challenges. However if your country has peaks over 3000m and is closer to the poles then you will in all likelihood have more severe conditions than Australian high country. Also, if because of altitude or distance, you cannot get to a decent coffee shop within a days walk from that area you might consider the ruggedness of your lightweight materials.

Another take on the Wilderness Equipment ‘First Arrow’ tunnel tent.

The guy who designs Wilderness Equipment (WE) is a bit of a legend in some circles. He has designed packs and equipment for Australian Special Forces, Australian Antarctic expeditions, various mining companies, governments etc. His stuff is known as bombproof expedition worthy gear. His expedition backpack harness with two independently rotating hip wings is rated by many people as the best in the world with daylight second - if carrying a lot of weight is what has to happen in your line of work. It is never light though. WE expedition equipment is designed to survive very rough country for extended periods of time for many years. Many people over the years have exhorted Ian to come up with a range of gear with lighter materials. For the last 15 years I have got responses usually along the lines of ‘equipment needs to last more than a couple of years of serious use’, ‘… ok for recreational users’… sustainability of products is better for the environment is another one. He has an ‘institutional’ range of gear for schools etc that is for beginners. This article is the first I have heard that the reason for the weight of expedition type tents as being ‘for novices’. Seemingly it is quite the opposite. ‘Novices’ generally do not buy expensive expedition tents that are twice the price of other, already expensive, tents in the store. Similar size expedition type tents from Macpac and Hilleberg are of a comparable weight and are using similar materials.

All WE designs using his engineering background are worth looking at closely and have many outstanding features.

The WE First Arrow is a case in point.

... another look at the specs... Stripped down for carrying 2.95kg sans ti pegs and 9in stakes. The WE site has 3kg listed as min weight which maybe is with pegs. This is the biggest of the tents tested. External width at 171cm (67.3in) height 120cm (47.25in) middle pole approx 95cm, end pole at 70cm (27.5in) Not sure how Caffin measured the interior in his review. My ruler says 110cm (43in) height at the peak, 90cm middle, 62cm (24in) at the foot end. 155cm widest internal to 110cm at the wide point of the foot end. So about 51cm each at the shoulder for 3 - tight and 2cm each less than Hilleberg 3 person - but ok … with height of 110cm x 155cm at the business end stretching to 90cm at the centre it allowed 2 big blokes and one 5’9” to cook and eat sitting up with a bit of care for two wet nights a few years back.

... another look at the design... I owned the Macpac Olympus and it is and was a very good tent despite the original design being from around the 80’s - like the WE. Here is why I sold it and bought the more expensive WE tent.

Like most high middle or non tapered tunnel designs the ventilation in the Macpac type tents can be a serious problem and a pain. It left a lot of condensation in the tent which froze or dripped onto the inner. The First Arrow is a tapered ie a rising roof design which is a very much drier tent.

“... the continuously rising shape of the tent to the high point in the cut-away eave provides the best possible still air convective ventilation and a direct exhaust path for cooking vapours rising from the vestibule. Even at low wind speeds the low pressure created over the main vestibule positively sucks air through the tent. With other designs the top part of the tent must flood with warm moist air before it reaches down to vent level.” … I would add wetting the inner in the process.

The venting is very clever system protected by ‘eyebrows’ that also do double duty as tension spreading for the multiple guy ropes for very stable end to end tensioning. The flow thru of this system is so efficient that this tent also excels in humid tropical downpours.

The ingenious vestibule design allows one or two entries or the entire front flap to zip down. The huge entry space allows for such easy entry and egress that helps make the livability of this design a joy to use. No more shuffling around when the second person needs to exit while the first person was cooking, a problem that occurs with most tunnels according to Caffin.

Small details
Like the Hilleberg and Macpac tents WE uses thick hard abrasion resistant guy ropes – less worries about guys abrading on rock ‘pegs’ and at 5000m base camps where average wind speed can be 40knots for days on end - these type of conditions are beyond an overnight winter storm at 50m above tree line – you might even describe it as 5th season perhaps.
WE’s guys are attached with doubled 4mm shockcord to better control wind forces and loosening guys. They are reflective for the entire length – higlighting guy ropes at low vis.
Like Macpac the guy attachment point is one very wide piece of fabric doubled over not two small ones.
Ian at WE is obsessive about new materials and ideas. Every few years there are updates and small redesigns. Gone is the silconised nylon fly to be replaced by a 30d ripstop polyester with silicone elastomer facing and polyether based PU back coating. A deep, unstressed tub floor, 100d nylon with 8,000mm HH coating that is folded not cut and sewn at the corners. These types of tubs are not light but they will handle rough sites where light materials won’t.
Scandium poles – marginally better performance than alu but, unlike carbon, will tend only to crease and fold when stressed too far that may allow for pole sleeves to rescue the situation.
Features like good big hardy zippers and decent pole sleeves like Macpac and Hilleberg that will stand up to some abuse that will inevitably occur in sub zero conditions at altitude with a decent alpine breeze where it just taken 2hours to travel 150m and the penalty for failure is extreme.
Like the Macpac it is easy to unclip the front end of the ground sheet to roll it back. In the WE this makes a very large vestibule space that two can sit and prep.
Custom alterations - eg snow skirts can be sewn in.

In many people’s view the Wilderness Equipment First Arrow is a premier expedition tent with design features that make it superior to others of this genre in important areas – albeit more expensive than most.

It seems to be a common thing that good designers are not necessarily the best marketers. Wilderness Equipment would be better known if the founder was more ‘accommodating’ and didn’t p!ss reviewers off so often and was able to explain his product to those selling it. Maybe engineers think that just because they have a good product it should sell itself.


First Arrow too much tent? WE also do a smaller 2 pole version - the Second Arrow tent - a 2 man tent about the same size and weight as a Hilleberg Nallo 2 or Macpac Minaret.2nd Arrow in snow

Yup. Me too. Same goes for One Planet.

Well, calling all that gear 'expedition' may be part of the perception problem. It IS sold in standard retail outlets, and yes, novices DO buy it. And they do stick the poles through the wall of the sleeve and demand their money back. (Source: Ian Maley.)

As to the other points you made - to each his own style. No problem.

Warmlite on 06/12/2012 13:03:10 MDT Print View

I have been using Warmlite tents now for over 20 years. Over the time I 'collected' 3 Warmlite tents (2,3 and 5) as well as several tarps and a couple tents from other manufacturers. Yet I keep coming back to these tents as my main goto tent.

First let's talk about the negatives:

1. I agree with you about the stitching 'look' but it has not affected me in practical terms while out there camping.

2. Also, in these days of taped seams, getting a tent that needs to be seam sealed is a bit of a drag.

3. If you absolutely must have a freestanding tent then a tube tent is obviously not for you.


Now the positives:
The Warmlite tents are by far the fastest pitching shelters that I have ever used and seen compared to what I own or what my friends own.

When you're being chased by mosquitoes in the wind river range or when you're caught by a rainstorm or when you're pitching a shelter in 30 knot winds - the warmlite tent is up in no time. Two hoops and 3 stakes, no messing with attaching a fly and you can retension the tent from the inside while out of the elements. I can have the tent pitched in 3 to 5 minutes.

There is absolutely no need for additional guy lines or for 3rd pole. The tent works fine as designed and thankfully this simplicity contributes to a quick up and down of the pitch.

I love the integrated fly design. The inner wall (second wall) shields you from any condensation issues. Typically one sleeps in the area between the hoops where the two walls are. The single walled entrance space is supposed to be the 'vestibule'. The space outside under the flap can store your shoes if you desire.

Because the tent is contain to one piece it is also very easy to dry it. Just hang it from a clothesline at home. This also helps keeping it clean of sand and debris. You can just shake it all out of the tent or just leave it hanging on the clothes line and gravity will take care of it.

The 2 series tent sleeps two people comfortably. We've had one night where we had 3 people side by side and a 5 year old child facing oposite way. By comparison the 4 person Big Agnes Copper Spur I have (and like) fits 3 people and one must rely on the tight vestibule space for equipment.

Last weekend I was pitching a tarp on a beach in strong winds. It was to be used for shade while the 3R waited to be pitched later for sleeping. The amount of stakes, guy lines and stakes and hardship that a single person needs to go through is almost comical when compared to the quick pitch of the Warmlite tents.

I've had a 2RD for over 20 years, 3RLW for 10 years and 5XW for over 5 years. This summer I will be replacing the 2 series with a new tent.
