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. A proprietary composite fabric, OSMO is made from 100% recycled polyester and nylon yarns and scores 4x better in water repellency than standard tent fabrics — all while stretching 3x less when wet. OSMO fabrics meet fire retardancy standards without the use of added chemicals and are treated with PFAS-free waterproofing.
Paired with the OSMO fly is a super-durable ripstop tent floor that can withstand the not-so-precious treatment that comes with life on the trail. Mayfly OSMO’s massive doors and generous headspace, however, feel anything but rough — there’s ample room for two to comfortably sit side by side.
Featuring NEMO-exclusive Elements™ hardware, this semi-freestanding tent offers an easy, intuitive setup that’s highlighted by the Axial™ corner anchors, which allow for connection and adjustment in one streamlined piece. A Divvy Cube™ stuff sack completes the package for efficient storing and splitting the weight with a friend.
- Bluesign® approved OSMO fly meets strict ecological and chemical requirements and has been produced with a minimum impact on people and the planet.
- Super-durable 68D PU ripstop floor withstands rough treatment on the trail and helps your tent last even more seasons.
- Divvy Cube™ rectangular stuff sack allows you to split the weight with your partner, but packs more efficiently in your backpack.
- Color-coded webbing and NEMO-exclusive Axial™ corner anchors create a smooth, intuitive setup experience.
- 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.
- Massive doors and generous headspace allow for side-by-side seating.
- Hubbed, pre-bent aluminum poles with a high-arching main pole to significantly increase volume at the head and foot ends.
- Tapered floorplan saves weight while giving backpackers space where they need it most.
