## Overview: Who Is the NEMO Hornet OSMO 2P For?

The NEMO Hornet OSMO Ultralight 2P Tent is built for weight-conscious backpackers who refuse to choose between a featherlight shelter and a livable one. Tipping the scales at just 2 lbs. 1 oz. at trail weight, it sits firmly in ultralight territory — yet NEMO has engineered in generous headroom, large doors, and volumizing features that make the interior feel genuinely spacious for two people. That makes it a compelling pick not just for solo gram-counters doubling up on gear, but for pairs tackling long-distance routes or multi-day alpine trips where rest and recovery matter as much as pack weight.

The headline upgrade over previous Hornet generations is the new OSMO fabric — a high-performance polyester-nylon ripstop blend made from 100% recycled, PFAS-free yarns. NEMO claims it delivers four times better water repellency and three times less stretch when wet compared to the original Hornet, two weaknesses that long-time fans of the earlier tent will be glad to see addressed. The result is a shelter that not only shaves grams but also holds up more reliably in the variable, three-season conditions — rain, humidity, and cold — that backpackers are most likely to encounter. With a price of $479.95 (currently on sale at $359.89), the Hornet OSMO positions itself as a premium but purposeful investment for anyone serious about going fast and light without roughing it more than necessary.

## OSMO Fabric & Sustainability: A Genuine Upgrade

The headline material upgrade in this generation of the Hornet is NEMO's proprietary OSMO™ fabric — a polyester-nylon ripstop blend that represents a meaningful, measurable step forward rather than a marketing rebrand. NEMO claims 4x better water repellency and 3x less stretch when wet compared to the previous Hornet's fabric, and both figures matter in real-world use. Superior water repellency means the rainfly sheds moisture more aggressively before it can saturate the fibers, which keeps the fly lighter during prolonged rain and maintains breathability longer. Less stretch when wet is equally important: a fly that sags and deforms under rain load can lose tension, allowing fabric to contact the inner tent canopy and wick moisture through to your sleeping space. With OSMO holding its geometry even when soaked, the structural integrity — and the all-important air gap between fly and inner — stays consistent throughout a storm.

The sustainability story woven into OSMO is just as compelling as the performance numbers. The yarns are made from 100% recycled materials and are entirely PFAS-free. This is significant because PFAS (per- and polyfluoroalkyl substances) have long been the go-to chemistry for durable water repellency (DWR) treatments in outdoor gear, but they are persistent environmental pollutants that accumulate in ecosystems and human tissue. NEMO's decision to formulate OSMO without them — while still achieving that 4x water repellency improvement — signals that the tradeoff between performance and environmental responsibility is increasingly a false one. The tent also meets flame retardancy standards without the addition of chemical flame retardants, another category of substances that have drawn scrutiny for health and environmental impacts. Rounding out the eco-credentials, the floor material carries bluesign® approval, a rigorous third-party certification that evaluates ecological impact, chemical safety, and resource efficiency across the entire manufacturing process.

For eco-conscious buyers, these aren't token gestures — they represent end-to-end accountability from raw yarn to finished shelter. For performance-focused backpackers, the reassurance is that none of these sustainable choices came at the expense of the tent's ability to keep you dry and comfortable in the backcountry. The Hornet OSMO makes a credible case that you no longer have to choose between gearing up responsibly and gearing up well.

**OSMO Fabric Certifications & Claims**
- **100% Recycled Yarns** — OSMO fabric is spun entirely from recycled materials, reducing reliance on virgin petrochemical inputs.
- **PFAS-Free DWR** — Water repellency achieved without per- and polyfluoroalkyl substances — persistent pollutants found in legacy DWR treatments.
- **bluesign® Approved Floor** — The floor material meets bluesign®'s strict ecological, chemical, and resource-efficiency standards.
- **Flame Retardant Without Added Chemicals** — Meets flame retardancy requirements through fabric construction rather than chemical additives.
- **4x Better Water Repellency** — Compared to the previous-generation Hornet fabric under equivalent wet conditions.
- **3x Less Stretch When Wet** — Maintains fly tension and structural geometry during prolonged rain, preserving the air gap with the inner tent.

## Livability & Interior Features

**Expert review — Marcus Wren, Senior Backpacking & Shelter Editor**
Rating: 4.5/5
Verdict: The Hornet OSMO punches well above its weight class in livability, delivering a suite of thoughtful interior features that most competing ultralight 2P tents simply can't match at just over 2 lbs.

At 2 lbs. 1 oz. trail weight, the NEMO Hornet OSMO sits squarely in the ultralight bracket, yet NEMO has clearly refused to treat interior comfort as a rounding error. The headline innovation is the patent-pending Flybar™ volumizing pole clip, which actively lifts the rainfly away from the inner canopy rather than letting it drape and sag. In practical terms, you feel the difference the moment you sit up — that 39-inch peak height reads better than the number suggests because the Flybar distributes fly tension evenly across the arch, preventing the canopy from closing in on you the way it does in most single-pole ultralight designs.

Complementing the Flybar are the volumizing guyouts that physically connect the inner tent to the rainfly and pull the sidewalls outward. Paired with triangulated corner struts that increase foot-end volume, the combined effect is a noticeably roomier feel across the 27.5-square-foot floor — particularly at the shoulders and feet, where ultralight tents tend to feel most coffin-like. If you've spent a night in a Big Agnes Fly Creek or an MSR Carbon Reflex, you'll immediately notice the Hornet OSMO feeling less claustrophobic despite comparable or lighter weight.

The two large doors are a genuine differentiator in this category. Many sub-2.5 lb. two-person tents cut corners with a single door, forcing one sleeper to clamber over the other. Here, each occupant gets their own entrance and a 7.1-square-foot vestibule — tight, yes, but functional for one person's pack and wet gear. The Gatekeeper™ clips are a small but surprisingly appreciated detail: a single-handed tie-back means you're not fumbling with toggles in the dark or the rain, and the vestibule stays neatly out of the way when cooking or accessing gear.

The dual-tone mesh canopy is another standout. White no-see-um mesh through the lower panels adds meaningful privacy compared to the all-black mesh found on many competitors, while a black mesh panel at the peak clears up enough at night to give genuine stargazing views — a feature that feels luxurious in an ultralight context. Nightlight Pockets™ round out the ambiance story: drop a headlamp in and the diffuser material strips out blue light, casting a warm, even glow that makes the interior feel far more livable than a bare lamp bouncing off nylon walls.

Where the Hornet OSMO falls slightly short is raw floor width — at 51 inches at the head tapering to 43 inches at the foot, two broad-shouldered sleepers will be cozy. The vestibules, while appreciated, are modest in size. But in the context of ultralight two-person shelters, these are inherent category compromises, and no competing tent at this weight offers as comprehensive a livability package. NEMO has done an exceptional job engineering comfort into a form factor that usually demands you sacrifice it.

## Pros and Cons of the NEMO Hornet OSMO 2P

**NEMO Hornet OSMO Ultralight 2P Tent**

**Pros**
- Impressively light at just 2 lbs. 1 oz. trail weight — competitive even among dedicated ultralight shelters
- OSMO™ fabric delivers 4x better water repellency and 3x less stretch when wet compared to the previous Hornet, meaningfully boosting wet-weather reliability
- Livability innovations like the patent-pending Flybar™ pole clip and volumizing guyouts pull the sidewalls outward, maximizing headroom and usable interior space for a tent this light
- Eco-conscious construction: OSMO fabric is made from 100% recycled, PFAS-free yarns, and the floor material carries bluesign® approval
- Divvy Cube™ rectangular stuff sack makes weight-splitting with a partner easy and fits neatly into the bottom compartment of a pack alongside a sleeping bag
- Backed by the NEMO Lifetime Warranty, adding long-term peace of mind to a premium investment

**Cons**
- Semifreestanding design means stakes are required for setup — not ideal for rocky or hard ground where staking is difficult
- No footprint is included in the box; purchasing one separately adds extra cost and pack weight
- 39-inch peak height keeps the tent aerodynamic and light, but taller campers may find sitting up or moving around inside feels cramped
- At $479.95 MSRP (currently on sale at $359.89), this is a premium-priced shelter that may stretch budgets even at a discount

## Packability & the Divvy Cube System

At 2 lbs. 8 oz. packaged and folding down to a compact 12.5 x 7.5 x 3.5 inches, the Hornet OSMO 2P is genuinely backpack-friendly — but what sets it apart from most ultralight competitors is how NEMO has thought through the packing experience with the Divvy Cube system.

The Divvy Cube is a rectangular stuff sack designed specifically to slip into the bottom compartment of a standard backpack alongside a sleeping bag — a slot that cylindrical stuff sacks notoriously waste with dead air space. Because the Divvy Cube is rectangular, it tessellates neatly next to a sleeping bag or quilt without leaving awkward gaps, making your pack load more efficient overall.

The real stroke of ingenuity, however, is the weight-splitting feature. The Divvy Cube is partitioned so that one partner can carry the poles while the other carries the tent body and rainfly, or any similar split that balances the load. For a 2 lbs. 8 oz. tent, that means each person carries roughly 1 lb. 4 oz. — a compelling number when shaving ounces matters most. Most competing ultralight 2-person tents in this category (such as the Big Agnes Copper Spur or MSR FreeLite 2) pack into a single cylindrical sack with no structured weight-sharing solution, leaving partners to improvise their own division.

At 12.5 x 7.5 x 3.5 inches, the packed size is competitive with other ultralight double-wall tents in this class, and the rectangular footprint gives it a real-world packing advantage over same-weight rivals that pack round and slightly smaller on paper but fit less cleanly inside a pack. For a tent that already impresses on the scale, the Divvy Cube system makes the Hornet OSMO 2P one of the most thoughtfully packable options in the ultralight backpacking market.
