Mayfly OSMO Lightweight Backpacking Tent 3-Person
Armed with NEMO’s top-performing OSMO fabric on the fly, Mayfly OSMO is a notably durable backpacking shelter for adventurers ready to hit the trail.
bluesign® approved OSMO fly meets strict ecological and chemical requirements and has been produced with a minimum impact on people and the planet.
High-performance, high-strength OSMO™ poly-nylon ripstop fabric has 4x longer lasting water repellency and 3x less stretch when wet. OSMO fabric is made from 100% recycled yarns that are PFAS-free and meet flame retardancy standards without the use of added chemicals.
Super-durable 68D PU ripstop floor withstands rough treatment on the trail and helps your tent last even more seasons.
Massive doors and generous headspace allow for side-by-side seating.
Divvy Cube™ rectangular stuff sack allows you to split the weight with your partner, but stows more efficiently in your backpack.
Hubbed, pre-bent aluminum poles with a high-arching main pole to significantly increase volume at the head and foot ends.
Color-coded webbing and NEMO-exclusive Axial™ corner anchors create a smooth, intuitive setup experience.
Tapered floorplan saves weight while giving backpackers space where they need it most.
Protected by the NEMO Lifetime Warranty.
