Armed with NEMOs 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 OSMOs massive doors and generous headspace, however, feel anything but rough theres ample room for two to comfortably sit side by side.

Featuring NEMO-exclusive Elements hardware, this semi-freestanding tent offers an easy, intuitive setup thats 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. Specs 2-Person
