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.

Re: A bit of a let down on 04/25/2012 19:58:24 MDT Print View

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
Stuart

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

Just wanted to add a thank you for all the effort you put forth in your designs and reviews of tunnel tents. My first tunnel is a Hilleberg that I love but is just a bit too heavy for summer use and compared to your winter tent...not quite as light. Cheers!

Thanks on 04/29/2012 13:28:55 MDT Print View

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: 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.
