NEMO Hornet OSMO Ultralight 3P Tent
Our Take
The NEMO Hornet OSMO Ultralight 3P Tent is a standout for weight-obsessed backpackers who want legitimate three-person capacity without the bulk, coming in at just 3.3 pounds with nearly 40 square feet of floor space.
Setup takes about five minutes and the large doors and vestibules give you room to stash gear without playing Tetris.
That said, the "3P" rating is optimistic if everyone actually wants elbow room, and you'll want to budget for a footprint since the floor fabric is on the thinner side.
At $580 it's not cheap, but for ultralight enthusiasts who prioritize packability over palatial living, the value proposition is solid.

What We Think
For backpackers who obsess over pack weight but refuse to sacrifice livability, the NEMO Hornet OSMO 3P occupies rare territory.
At 3.3 pounds for a three-person tent, it delivers genuine room to move without the gram-counting guilt that usually comes with spacious shelters.
The Hornet OSMO 3P scored a 8.7 overall, earning high marks across nearly every dimension that matters on the trail.
Space & Comfort
The 39.7 square feet of floor area and 44-inch peak height create vertical walls that make this tent feel dramatically larger than its footprint suggests.
Here's the honest reality owners consistently report: despite the "3P" designation, this tent fits two people comfortably with gear, not three adults expecting personal space.
That's not a knock, it's just how ultralight three-person tents work in practice.
The two large doors eliminate the dreaded climb-over-your-tentmate situation, and the dual 8.6 square foot vestibules provide genuine gear storage that keeps muddy boots out of your sleeping area.
Space & Comfort scored a 9.0.
Ease of Use
Owners consistently report that the three-minute setup time is real, with several mentioning they nailed an intuitive pitch on their very first attempt.
The semi-freestanding design does require stakes for a proper pitch, so you'll want to scout your campsite for stakeable ground.
NEMO's Gatekeeper one-handed door tie-backs are the kind of small detail that matters at 2 AM when nature calls.
Ease of Use scored a 9.0.
Quality & Durability
The proprietary OSMO fabric blend is the real story here, combining polyester's dimensional stability with nylon's strength.
Unlike traditional nylon flies that sag and drip condensation onto your face when wet, OSMO resists stretching and dries significantly faster.
A recurring theme in owner feedback, however, is that the 0.6 oz ripstop floor fabric is genuinely delicate, and many recommend budgeting for NEMO's footprint or a DIY ground sheet, especially on rocky terrain.
That's the required tradeoff for sub-3.5-pound shelter weight.
Quality & Durability scored a 8.5.
Weather Resistance
The 1500mm hydrostatic head rating on the floor handles typical three-season conditions confidently.
The OSMO rainfly sheds water without the sag that plagues nylon in sustained rain, which matters more than raw waterproof ratings in real-world storms.
Triangulated guy-outs help maintain structure in wind, though this remains a three-season shelter, not a storm bunker.
Weather Resistance scored a 8.0.
Value for Money
At $580, the Hornet OSMO 3P sits in premium ultralight territory, but the price-per-pound math is compelling.
The Big Agnes Tiger Wall 3 Carbon shaves another pound but costs $750 and uses more fragile materials.
If you're splitting weight between two backpackers, the NEMO Hornet OSMO 2P at $480 and 2.1 pounds might be the smarter play for couples who don't need the extra vestibule space.
The lifetime warranty adds long-term confidence to the investment.
Value for Money scored a 9.0.
User Reviews
Owner feedback runs consistently positive, with the most common praise centering on the weight-to-space ratio and genuinely quick setup.
The Nightlight Pockets that diffuse headlamp glow into ambient light earn surprising loyalty from long-distance hikers.
User Reviews scored a 9.0.
Who It's For
This tent makes sense for backpackers who want legitimate two-person livability at a weight that won't punish you on long approaches.
It's ideal for couples who value elbow room and gear organization, or solo hikers who want palace-like space without carrying palace-like weight.

The Bottom Line
The NEMO Hornet OSMO 3P scored a 8.7 because it solves the ultralight tent's oldest problem: feeling like you're sleeping in a coffin to save ounces.
Budget for the footprint to protect that delicate floor, and you'll have a shelter that earns its spot in your pack for years.
For weight-conscious backpackers who refuse to compromise on livability, this is the tent.
