The inaugural product that launched Nemo's Endless Promise® collection — the Nemo Women's Forte 20 Regular Endless Promise is 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.
- Classic Spoon® shape adds room at elbows and knees for versatile, unrestricted comfort
- Thermo Gill™ vents extend the comfort range with a multistage zipper system
- Blanket Fold™ draft collar blocks cold air or releases excess warmth for fine-tuned temperature control
- Zerofiber™ 800 lightweight synthetic insulation made from 100% post-consumer recycled content offers best warmth-to-weight ratio
- Shell and lining of bluesign® approved 20D 100% recycled polyester ripstop for a buttery-soft, ultra-plush sleep experience
- Hood and footbox reinforced with recyclable material treated with PFAS-free waterproofing to prevent tent condensation from soaking into the bag's fabric
- Zip two Fortes together (opposing zipper sides) to create a double sleeping bag
- Available in Regular, Regular Wide, and Long
