Spacious, dependable, and thoughtfully refined – a standout for backpackers wanting comfort 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
The 2025 update to the Dagger OSMO 2P is a quiet triumph. Thanks to a revised pole structure, the tent now offers more headroom at the doors and centre, improving comfort, especially when sitting up or moving inside. The expanded vestibules are also a welcome change, giving just enough extra space to manage wet kit without feeling cramped.
At 1548g (excluding pegs and bags), it’s not the lightest in its class, but it earns its weight with excellent liveability. The pre-bent aluminium poles make pitching quick and intuitive, and the new Axial anchors are a clever touch – genuinely usable one-handed. The OSMO fabric continues to impress: durable, eco-conscious, and resistant to sag in damp conditions. It’s held up well in persistent rain and has remained taut overnight.
Inside, the Nightlight Pockets are more than a gimmick – they create a warm, diffuse glow that’s great for reading or winding down. The Landing Zone gear tub in the porch is another detail I didn’t realise I needed until I used it — it keeps kit dry and organised without having to drag it all inside the inner, especially in foul weather.
