NEMO Hornet Elite OSMO is the benchmark solo ultralight tent. We looked at the OSMO fabric innovation and compared it to competing 1-person options.
Who it's for
Buy this if: Solo thru-hikers or fastpackers who prioritize weight above all else.
Skip this if: Anyone who backpacks with a partner or needs a wider sleeping floor — the 1-person width is strict.
In practice
OSMO Fabric
Standard ultralight fabrics use silicone-coated nylon, which absorbs 1-3% moisture by weight in high humidity or rain. Over a multi-day trip, this adds measurable pack weight. OSMO blends polyester (moisture-resistant) with nylon (flexible, packable) — field tests show 0.3% moisture absorption under the same conditions.
