What Our Gearhead® Experts Are Saying:"I reach for the Forte Endless Promise 20F on chilly overnights where I want comfort, warmth, and a clear conscience. It’s roomy without feeling bulky, and the Classic Spoon shape lets me move naturally. The Thermo Gills make it versatile in shifting temps, and the fully recyclable design is a game changer."Restful nights start with smart design, and the Forte Endless Promise 20F Sleeping Bag gives us both comfort and peace of mind. Built around NEMO’s Classic Spoon™ shape, this sleeping bag offers extra room at the elbows and knees—perfect for side sleepers who don’t want to feel confined. With a temperature rating down to 20°F, it’s made for shoulder-season backpacking, high-altitude camps, and frosty spring starts.Filled with 100% recycled Zerofiber™ 800 synthetic insulation, the Forte retains heat efficiently while maintaining packability and wet-weather performance.
