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.
