Nemo Dagger OSMO 3P Tent

Jump to: Our Verdict / Features / Specifications

The Dagger OSMO 3P is built for shared journeys without compromise.

Nemo says: 

The most livable backpacking tent in our line just got a little roomier. Dagger OSMO now features an updated pole structure that adds 4 inches to the door height, 2 inches to the peak height, and 22% more usable space to the vestibule. This maximized interior offers downright luxurious downtime in camp and comes at no extra weight cost.

Rounding out the improved experience is NEMO’s custom Elements™ hardware suite, featuring the Axial™ corner anchor for one-handed setup and tensioning. The updated hardware and poles are paired with solution-dyed OSMO™ fabrics on the fly and floor that promise 4x longer lasting water repellency, 3x less stretch when wet, and a 20% higher strength rating than similar fabrics. Made from 100% recycled yarns for reduced waste, this OSMO fabric also requires less water for the dyeing process. These sustainability efforts combine to earn Dagger OSMO certification as a bluesign® product backpacking tent — the industry’s first at the time of launch.

Features like the Divvy Cube™ stuff sack, Landing Zone™ waterproof storage tub, Nightlight Pockets™, and one-handed Gatekeeper™ door clips remain staples of this backpacking favorite, equipping it well for both relaxed car camping and backcountry treks. Between the feature set, ample interior, and light weight, Dagger OSMO is a true one-tent wonder for adventures of all kinds.

Our Verdict

This spacious and dependable backpacking tent balances comfort, weather protection, and sustainability with a low packed weight.

Roomier, tougher, and still light enough for the trail, the updated Dagger OSMO 3P leans into comfort. The revised pole geometry lifts the door and peak height and increases vestibule volume, making this one of the more liveable options in its class. For three people, it’s workable for a night or two; for two people on a longer hike, it’s ideal.

The new Axial corner anchors make setup straightforward, even solo, and the pre-bent pole structure holds tension well in wind. The OSMO fabric is durable, impressively stable when wet, and PFAS-free. It’s also made from 100% recycled yarns and dyed in a way that cuts down water and energy use, which is a meaningful step forward for sustainability.

At 1774g, it’s not ultralight (you can split the load between your camping buddies), but it still feels trail-ready for its floor space and feature set. An innovative layout, generous storage options, and improved ventilation round out the tent.
