The Western Mountaineering NanoLite Quilt is an ultralight down top quilt for fast and light adventures where every gram matters. 850+ fill power goose down and a 12D ExtremeLite shell deliver impressive warmth to 3°C from around 370g.

Adjustable pad straps hold the NanoLite securely to your sleeping mat for a custom fit, better heat retention and fewer drafts, an insulated draft yoke stops heat escaping around your neck, and the sewn footbox keeps your feet warm with a simpler, more efficient design. The 12D ripstop nylon shell and 10D liner are ultralight, breathable and soft against the skin, and it packs to 15 x 25cm. Choose the NanoLite for thru-hiking, fastpacking, summer alpine use and layered sleep systems where you want the lowest possible weight.
