What Our Gearhead(R) Experts Are Saying:"I've used the Forte Endless Promise 20F on shoulder-season trips and early spring backpacking-it's roomy in all the right places and warm even on frosty mornings. I love how the Classic Spoon shape gives me space to shift positions without feeling constricted, and the Thermo Gills are surprisingly effective for dumping heat when temps rise."When temperatures dip, we turn to the Forte Endless Promise 20F Sleeping Bag for reliable warmth and exceptional sleep, night after night. NEMO's Endless Promise platform means this bag is fully recyclable at the end of its life, but that doesn't mean they held back on performance. With 100% recycled Zerofiber(TM) 800 synthetic insulation, a PFAS-free DWR, and a shell made entirely from recycled materials, this bag keeps us warm while cutting down on waste. The Classic Spoon(TM) shape gives us extra room at the knees and elbows for comfortable side sleeping and natural movement, while Thermo Gills(TM) let us fine-tune ventilation without unzipping. A generously sized Blanket Fold(TM) draft collar tucks in warmth, creating a cozy cocoon on cold nights. Whether we're heading out on late-season backpacking trips or camping where frost is in the forecast, the Forte 20F has the warmth, roominess, and design-forward features to help us sleep soundly in the wild.
