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

Introduction

Exped Aries Mesh Review - 1

The Exped Aries Mesh is a straight two-pole two-man double-skin tunnel. First, the specifications.

Brand Exped (Switzerland)
Model Aries Mesh
Poles 2, DAC Press-Fit 9 mm TH72M
Skins 1
Fly Fabric 40 d PU-coated, UV-resistant, ripstop polyester
Entries 1
Vestibules 1
Persons 2
Listed Weight 2.67 kg (5 lb 14 oz)
Tent Weight 2.92 kg (6 lb 7 oz)
Pole Weight 392 g (13.8 oz)
Stakes, Weight 13, 166 g (5.8 oz)
Stuff Sacks 105 g (3.7 oz)
MSRP US$350

It would seem that the listed weight is rather less than the measured weight. It is not clear what the listed weight was meant to include.

Details

This is a fairly 'stock standard' two-pole two-man double-skin tunnel tent, but built with Swiss attention to detail. For instance, the pole feet go into webbing pockets lined with spare repair sleeves rather than simple eyelets. It is not all that lightweight, but it is quite rugged. That includes the mesh inner tent - the mesh is also quite rugged. However, the mesh will not stop a breeze, which is why this tent is listed as a single-skin tent.

The fly fabric is listed as 'flame retardant.' This is to comply with laws in some states. It's an extremely stupid idea as the flame retardant won't prevent a melt-down but is reported to reduce the fabric strength quite severely. Too much political correctness. The groundsheet is listed as being waterproof to 5 m water head (which is good).

Exped Aries Mesh Review - 2

The interior of the tent has reasonable floor space for two, and very reasonable headroom. The rear end of the tent does slope down, making the very rear less useful for sitting, but there seems to be a fair bit of floor space in the middle with high headroom. The sides go straight up and the middle is wider than most, so the middle region is quite usable. You would certainly be able to pack a lot of gear down the sides of your mats.

The tent pole stuff sack is a work of art, with separate pockets for the poles, the stakes, and the spares. The 'spares' include a repair sleeve, a slider for the zips, self-adhesive repair fabric for the fly and the groundsheet, and some spare mesh for the inner tent. The stakes are fairly wide-angle with folded-over ends which are comfortable to the hand. The aluminium is a bit soft, making it a bit difficult to hammer them in. The literature says 16 stakes; I am fairly sure I found 13.

The guy ropes are about 2.5 mm diameter, with sparkles for visibility at night. They have toggles as shown here. You need to slacken the tension off the guy with one hand to slide the toggle along the string, but that is easy to do. You can see the toggle here and in the photos below. You can also see in the photos below a yellow 'flag' on each guy rope. Actually, the 'flag' is a little nylon pocket into which you can stuff the coiled-up guy line. Very tidy people, the Swiss. Also, I am sure the flag may help prevent others from falling over the guy!

Exped Aries Mesh Review - 5
You can put a bit of lengthwise tension on this tent, which is good for handling storms. Also very nice is the way the guy ropes are used: they are 'doubled' (like mine) as shown here. That is, they attach at two points: low and high. That provides a lot of support to the tent poles when the wind goes side-on.

Exped Aries Mesh Review - 6
There's a loop of light webbing with a welded ring threaded on it. You can just make out the ring in the photo here (the stake goes through it). On the rear corners, the webbing goes back under the metal ring to thread through another (plastic) ring (not pictured) and then to anchor the corner of the groundsheet. The webbing looks kinky: it has two strands of bungee cord inside it to maintain tension. I will express some doubts here: I would not bother with the bungee cord at the rear end, but it doesn't matter as you can pitch the tent tight enough that the load goes on the webbing. At the downwind end, the anchors are plain loops of webbing: one loop on the side panel and one loop on the corner of the door.

Exped Aries Mesh Review - 7
The tent poles are fairly stock DAC ones, although the 9 mm diameter is definitely rugged. The 'far end' is captive inside the pole sleeve, making it easy to thread the poles, but you can only do this from one side. What is interesting is how the 'free' end is retained, as mentioned right at the start. You slacken off the tension webbing, thread the end of the pole into an aluminium sleeve inside the webbing pocket, and then tension up the sleeve with the webbing. All of that is visible here. The cute trick is that you can extract the aluminium sleeve and use it for emergency pole repairs if you need to, and the webbing is still adequate to hold the end of the pole. Swiss ingenuity.

Exped Aries Mesh Review - 8
There is only one vestibule on the tent, but it is large enough for cooking in comfort. It would be a little cramped if you had to store two packs there as well, but you could manage. It might be a little tricky if the second person needed to exit to the loo while the first person was cooking, but that problem occurs with most tents.

Exped Aries Mesh Review - 9
There is provision for ventilation, as may be seen in the two photos above, but it is a bit limited. The ventilation over the door can be unzipped - why is not clear. The hood there is stiffened so the hole remains open. The rear end vent is similar but not zipped. What is neat is that you can close the ventilation down a bit, as shown here. Now, if they had made the downwind vent mesh without the zipper and the up-wind mesh zipped, you could reach out and alter the hook and loop attachment. That would have made a bit more sense. Odd.

Summary

Ideally, I would have liked to review the Sirius II instead of the Aries mesh, as the Sirius is a genuine four-season double-skin tent. However, it is not marketed in the USA. So we have the Aries Mesh: a three-season tent. As you might expect from a Swiss company, it is well made and rugged, although you do pay for the strength with the weight. Could you use this tent in the snow? Yes, keeping in mind that you may need to block spindrift from entering.

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?

I think you may be looking at the USA web site? Try the Swiss web site - their home country. Both tents are still current there.

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.

Cheers

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?

Hi Jason

ID Traverse 2 is interesting, but floorless. A bug liner is available. I actually have one on the floor here, but so far the company has not replied to any of my questions about some VERY strange features in the tent.

Hi Miguel

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?

Cheers
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...
