The NEMO Hornet Elite OSMO 2 is the ultralight specialist of this list, delivering full double-wall protection, two doors, and two vestibules at roughly 2 pounds, a remarkable feat. Reviewers love it for solo use and fast-and-light couples, praising its low weight and easy setup, but they consistently warn that it is a tight squeeze for two adults and that its gossamer fabrics need care. If your priority is shaving weight and you understand the trade-offs, it is superb; for roomy two-person comfort, look higher up this list.

Ultralight Weight and Protection
The Hornet Elite OSMO 2's headline achievement is fitting a full double-wall, two-door, two-vestibule tent into roughly 2 pounds. Treeline Review sums it up: at 2 pounds for two people and one of the best compact sizes out there for a tent of its size, the Hornet Elite OSMO is a good shelter for couples or for solo backpackers who want a luxuriously-featured tent. That is an extraordinary weight for a tent that still offers true double-wall protection rather than a minimalist single-wall design.
Switchback Travel echoes the point, noting that for just over 2 pounds, the Hornet Elite provides reliable double-wall protection alongside two doors and vestibules and a fairly easy set-up process. For thru-hikers and fast-and-light backpackers obsessed with base weight, this combination of features and featherweight is the entire appeal.
The double-wall distinction is important. Many tents that hit this weight do so by going single-wall, which saves material but invites condensation problems, since there is no separate fly to keep interior moisture off your sleeping bag. The Hornet Elite keeps a true inner tent and a separate rainfly, so it manages condensation far better than a single-wall shelter of similar weight while still landing in genuine ultralight territory. That is the engineering achievement that justifies its existence.
Setup and the OSMO Fabric
Ultralight tents often pay for their low weight with fiddly, frustrating setups, but the Hornet Elite avoids that trap. OutdoorGearLab praises it for delivering genuinely ultralight weight without frustrating setup rituals or flimsy materials, with the OSMO fabric's resistance to wet sag being a real advantage. The hubbed pole goes up quickly and the structure is more intuitive than many tents in its weight class.
The OSMO poly-nylon fabric is the same technology that makes the Dagger so weather-worthy, here applied in an even lighter form. Its key benefit in an ultralight shelter is that it resists the overnight sag that causes lesser nylon flies to droop and touch the inner tent in the rain, helping the Hornet stay taut and dry despite its minimal materials.
That sag resistance matters more on an ultralight tent than almost anywhere else. Featherweight nylon flies are notorious for absorbing water, stretching, and sagging onto the inner canopy overnight, which then wicks moisture inside, exactly the failure mode that gives ultralight tents a bad reputation in storms. By building the Hornet Elite from OSMO, NEMO addresses that weakness directly, so the tent holds its pitch through a wet night far better than its weight would suggest. For an ultralight tent, weathering a storm without the fly collapsing onto your sleeping bag is a genuinely meaningful advantage.
Comfort and Fit for Two
Here is the central caveat: the Hornet Elite is technically a two-person tent, but nearly every reviewer recommends it primarily for solo use. With 27.3 square feet of floor and a narrow width, it is a tight squeeze for two adults. Treeline Review is candid that this wouldn't be the tent to share with a random person you just met in a backpacking meetup group, because the dimensions require compatible, close sleeping partners.
As a solo shelter, by contrast, it is luxurious, offering one person plenty of room to spread out and organize gear at a weight that rivals minimalist one-person tents. Couples who are genuinely comfortable sleeping close and are willing to trade space for weight can make it work; everyone else should treat it as a premium one-person tent that can occasionally sleep two.
The two doors and two vestibules are what make even that occasional two-person use tolerable. In a tent this narrow, having a separate door and covered storage area for each person means you are not constantly climbing over your partner or fighting for vestibule space, which would be unbearable in a single-door ultralight tent. It does not add floor width, but it does add livability at the margins, and for a committed pair on a fast trip that can be the difference between workable and miserable.
Where It Falls Short
The flip side of ultralight is fragility. Reviewers consistently warn that the Hornet Elite's lightweight fabrics and components require more care than traditional backpacking gear, and that its minimal footprint and narrow width means you have to like your hiking partner a lot. This is a tent to pitch carefully, use a footprint with, and handle gently; it will not tolerate the abuse the MSR Hubba Hubba shrugs off.
Price is the other sticking point. At around $600 it is one of the most expensive tents in the category, which is a lot to pay for a shelter most owners will use solo. You are buying extreme weight savings and clever engineering, not space or ruggedness, and that value proposition only makes sense for a specific kind of weight-focused backpacker.
There is a logic to that price for the right buyer, though. A dedicated ultralight one-person tent of comparable quality is not dramatically cheaper, and the Hornet Elite gives a solo hiker a luxuriously roomy one-person experience plus the option to occasionally squeeze in a partner, all at a weight that competes with single-person shelters. Framed that way, the cost is easier to swallow. Framed as a two-person tent, it looks expensive and cramped, which is why setting expectations correctly is everything with this model.
How It Compares to Alternatives
The Hornet Elite is the weight extreme of this list. It undercuts the Big Agnes Copper Spur UL2, MSR Hubba Hubba LT 2, and NEMO Dagger OSMO 2 dramatically on the scale, but every one of those tents is more comfortable and more durable for two people. Its closest relationship is with its sibling the Dagger OSMO 2, which shares the OSMO fabric but takes the opposite philosophy, prioritizing space over grams.
Even the budget Naturehike Cloud Up 2, which is also cramped for two, weighs more than the Hornet while costing a fraction as much, so the Hornet's pitch is purely about premium ultralight engineering. Choose it for what it is, the lightest reasonable double-wall option, not for two-person living space. The premium you pay over the Naturehike buys ounces and fabric technology, not square footage, which is the right trade only for a hiker who genuinely values weight above all else.
Who It's Best For
Choose the NEMO Hornet Elite OSMO 2 if you are a solo backpacker who wants a roomy, full-featured one-person tent at near-record-low weight, or a weight-obsessed couple on a long thru-hike who will happily tolerate tight quarters to carry the lightest possible double-wall shelter. It rewards careful, ounce-counting users.
Look elsewhere if you want genuine two-person comfort (the NEMO Dagger OSMO 2 or Big Agnes Copper Spur UL2), durability for rough terrain (the MSR Hubba Hubba LT 2), or a low price (the Naturehike Cloud Up 2). For the wrong user it is an expensive, cramped, fragile tent; for the right one it is a marvel.
The honest way to think about the Hornet Elite is as a specialist tool rather than a generalist tent. Just as a trail runner is the wrong shoe for a rugged off-trail scramble but the perfect choice for fast miles on a graded path, the Hornet Elite is the wrong tent for a relaxed two-person car-to-camp weekend but the ideal shelter for a weight-obsessed solo thru-hiker counting every ounce. Buy it for that mission and it excels; buy it for the wrong one and it will disappoint.

How it compares
By far the lightest tent here, undercutting the Big Agnes Copper Spur UL2, MSR Hubba Hubba LT 2, and NEMO Dagger OSMO 2 by a wide margin, but also the least livable for two. It shares NEMO's OSMO fabric with the roomier Dagger OSMO 2. The budget Naturehike Cloud Up 2 weighs more and is also tight for two, but costs a fraction as much.
Who this is for
At a glance: Solo backpackers who want a luxuriously roomy one-person shelter, and weight-obsessed couples on long thru-hikes who will tolerate tight quarters to carry the lightest possible double-wall tent.
