Forte 20 Long Endless Promise

The Nemo Forte 20 Regular Endless Promise is the inaugural product that launched Nemo's Endless Promise® collection — a beloved 3-season bag for the backcountry that stands out in sustainability, performance, and comfort. Nemo's Classic Spoon® shape offers more room at the knees and shoulders for a less-constricted feel, while two-stage Thermo Gill™ zippered vents and a Blanket Fold™ draft collar deliver an extended, fine-tunable temperature range. Made with a suite of recycled fabrics and filled with 100% recycled Zerofiber™ 800 synthetic fill, Forte is fully recyclable at the end of its life — just send it back to Nemo, and they'll handle the rest.
