Our Take
The NEMO Mayfly OSMO 3 hits the sweet spot for backpackers who want a lightweight tent without sacrificing long-term durability.
The specialized OSMO fabric stays remarkably taut and dry in the rain, while the heavy-duty 68D floor is tough enough to handle rocky ground or camping with dogs.
Its intuitive, color-coded setup and massive doors make life on the trail much easier, providing a spacious and well-ventilated home for your backcountry adventures.
