Our take on the Nemo Mayfly OSMO Lightweight Backpacking Tent

The Nemo Mayfly OSMO is a three-season backpacking tent that uses OSMO poly-nylon ripstop fabric, which Nemo claims has four times longer-lasting water repellency than standard coatings. It has two doors and two vestibules, making it a practical choice for couples or small groups who want easy access and gear storage. At 3 lb 10 oz trail weight for the 3-person version, it is competitive with other lightweight tents, though not the absolute lightest. Reviewers praise its weather resistance and livability, but some find the fabric a bit crinkly and the tent tight for three full-size adults.
