NEMO Equipment Mayfly OSMO Footprint

The NEMO Mayfly OSMO Footprint is a tent-specific ground sheet cut to the floor dimensions of the NEMO Mayfly OSMO, sitting between the tent floor and the ground. Its abrasion-resistant polyester absorbs wear from grit, roots and rock so the tent's own floor doesn't take that damage, extending its life and cutting the risk of punctures on rough or gravelly pitches. Because it's cut to the Mayfly OSMO's exact shape rather than a universal size, it only fits that tent — check compatibility before buying if you have a different model. It adds a little pack weight over pitching directly on the tent floor, worth it on abrasive ground and less necessary on soft grass or sand.
