Nemo Forte Womens 35 Endless Promise Sleeping Bag Sleep How You Actually Sleep Most sleeping bags are built around the assumption that you sleep on your back. The Forte Endless Promise(R) was made for the other seventy percent. The Classic Spoon(R) shape offers more room at the knees and shoulders for a less-constricted feel that's still compact, so you can shift positions through the night without fighting the bag. Two-stage Thermo Gill(TM) zippered vents give you an extended usable temperature range that can be fine-tuned from within, and the Blanket Fold(TM) draft collar lets you tuck in for warmth or leave unfolded to release excess heat. It's filled with 100% recycled Zerofiber(TM) 800 synthetic fill, which stays warm even when wet. NEMO takes full responsibility for all Endless Promise(R) products, from production to end of life, and designs them for total recyclability to keep them out of the landfill.
