The Stephenson's Warmlite is a specialty tent that is made in the USA and offers tons of customs options. The Warmlite has tons of interior space for hanging out in and storing your gear — at an exceptionally low weight. Its tunnel-shaped design is super durable and is easy to pitch on snow, sand, or in more-established sites, but can be a little trickier in tight, rocky areas.
While this is our Top Pick for Backcountry Touring, it also works well in established campsites where there are enough options for good staking.
Ease of Set-Up
The Warmlite Two-Person Tent uses a bomber non-freestanding tunnel design with two custom-made pre-curved poles. They insert into full-length sleeves with a unique system of holding the poles in place. Unlike most tents, there isn't a mechanism or grommet to cinch the poles down once inserted. Instead, you must push hard and slip the end of the pole into a pocket reinforced by webbing at the end of the sleeve.
This design is bomber, although it did require a little bit of a learning curve, and remained slightly more challenging than most models. This tent uses only three stakes, and because there aren't any guylines, they must be bomber to get the whole thing taut. This was easy to achieve on snow when using skis or an ice axe, but it was occasionally challenging on firmer or rockier tent sites.
With very high tension applied to the tent lengthwise, it is possible to achieve a very taut and bomber pitch despite the fact that the tent only has three tie-out points. Yep, you heard it, that's right, there are only three tie-out points, and all of them are at ground level. Therefore, it's imperative that each one be BOMBER when using very sturdy ground anchors like skis or ice axes in the snow.
This tent is easier to stake out properly in snow than in dirt and rocks.
Then the tent is capable of handling very high winds; in fact, we know several people whose Warmlite Two-Person tents have withstood 50mph winds like a champion. We especially like that the poles go underneath the outer tent because it gives a very sheer, smooth look, perhaps helping the tent slice through wind even better. Full-length pole sleeves support the poles very well once inserted. With its relatively low peak height, it is quite bomber when well-anchored, which is easy to achieve in the snow.
However, if it's windy out, you must plan or take the appropriate time to pile rocks on top of the stakes to keep this tent bomber. It's worth noting that for $35, Stephenson will add "Wind Stabilizers," which would undoubtedly make the Warmlite Two-Person Tent even more bomber.

The Warmlite Two-Person Tent has an integrated vestibule (with a connected floor) in the front of the tent. The interior is extremely spacious considering how light the tent it. Floor area is a massive 42 sq. ft., but unfortunately you can't sit up in all of it. The tent tapers both in peak height and in width towards where most people's feet will be. As a result, while there is plenty of room for your gear and the tent feels spacious, it's hard for two people to sit up and face each other. On the higher front end, one person should be able to sit straight up as long as they're not too tall.
Overall, the Warmlite has far more room than the comparable in weight MSR Advance Pro or Black Diamond Firstlight, at least when lying down. The middle portion of the tent uses two walls, while each end is a single wall; the central portion helps reduce condensation and increase warmth. The standard door is somewhat small, and in wintery conditions, partly due to its design, is slightly more challenging to use than other models. For $22.50, Stephenson offers a larger door; we'd recommend it unless you're out to save every ounce possible.
There is a lot of interior space, but it tapers at the end, and you can't really sit up back there.
Overall, we think the Warmlite Two-Person Tent is a very long-lasting tent but it does have some durability issues.
Take note that the custom poles have very thin walls (.3mm), perhaps 30-40 percent thinner than the average pole used in the winter tents tested here (mostly .45mm-.55mm). They are susceptible to damage and require some care when handling and packing. Once inserted into their sleeves (which support the poles extremely well), they have proven to be quite strong, but again you'll want to be careful when inserting and tensioning the poles while pitching the tent. The 30D silicon-coated ripstop nylon fabric is above average for UV resistance and will hold its water-resistance for a long time.
The poles are very delicate. The walls bend easily, and then the two sections do not line up well.
We were slightly let down by the quality of construction on the Warmlite Two-Person Tent. There seemed to be a lack of attention to detail in the cutting of fabrics and their stitching; a handful of the seams weren't straight, several of what we consider critical seams were only single stitched, and there were places where we were surprised there was no hemming at all. See the photo below.
Sloppy cutting and stitching.
The body and poles weigh a mere 3 lb 4 oz, making this one of the lightest tents we tested. Its minimal weight wasn't as low as the MSR Advance Pro or Black Diamond Firstlight (which featured a minimum weight of 2 lbs 13 oz), but its packed weight was very comparable and offered a lot more interior space than either of these tents.
This is also one of the most packable tents; it could not compact down quite as small as the Firstlight but it offered more than 25% extra floor space.

The Warmlite Two-Person Tent has certain advantages, primarily being that its light and packs down small. It also offers a pretty significant amount of floor space, but it is not very versatile. It doesn't come with a bug mesh door but does offer decent ventilation. It isn't that great when set up in rocky campsites or other places where it might be difficult to stake its three anchor points out securely. However, for camping on snow or more designated spots, it will work for a variety of applications where weight and a low packed volume are high on your priority list.
We do think if you sprung for some of the extra features, like the more massive door and side windows, this tent would be more versatile.
The vent is small and didn't provide the best ventilation.

, you can also choose from a host of custom features that increase strength and/or comfort.
$66: Side Windows, suitable for viewing and cooling in a summer breeze
$22.50: Large Door, more accessible entry into the tent, comes with one door
$175: Endliner, which is rarely needed, except for in extreme conditions
$35: Wind Stabilizers, helpful if the wind is higher than 60mph
Some of this tent's features are ingenious because they are so simple and effective. The rear vent pulls open and closed with a small cord, though the front door design leaves considerable room for improvement.
We liked the rear vent on this tent. It is also highly customizable depending on your needs.
The Warmlite Two-Person Tent is our favorite tent for backcountry ski touring and works well for backpacking because of its above average amount of interior space and its tunnel design. These designs make it bomber when anchored with skis, shovels, or poles (in snow). Considering this, we do think that overall, the Warmlite is best for winter adventure races, ski touring, or summer alpine climbing. While it is indeed lightweight, it does not have any bug netting, and there could be more ventilation, making it a poor option for low-elevation and potentially humid thru-hiking or lightweight backpacking. If you're looking for a tent that does it all and you do not mind throwing down some money, check out our Editors' Choice award-winning model, the Hilleberg Jannu.
The Warmlite in its preferred habitat, a big snowfield. This was our Top Pick for Ski Touring.
At $899, this made-in-USA tent is quite customizable. We do think the bigger door, and mid-point wind stabilizers are worth the extra dollars. If you want a tent for more than just ski touring and mountaineering, you should consider adding the side door. Even if you're dropping close to $900, the Warmlite Two-Person Tent remains a respectable price and only a little more expensive compared to its competition. The only things we are down on are its minimal versatility and its potentially fragile poles, as we felt like we truly had to be careful with them.
The Stephenson's Warmlite is a cool, albeit specialized, 4 season tent. It provides the most interior space for the weight. It's best for camping on snow or backpacking in established sites, where it pitches easily with three anchors points. We have used it on an extended alpine traverse while camping exclusively on rocky alpine and sub-alpine terrain in less established sites. While it works in those situations, it takes more effort. It's worth noting that with this tent, you get a lot of space for that effort compared to the bivy-style models in our review that are of similar weights.
