Forte Endless Promise 35 Sleeping Bag combines side-sleeper comfort with sustainable insulation
What Our Gearhead® Experts Are Saying:
"This is my go-to for summer backpacking. It’s spacious, warm enough for most nights, and the venting is clutch when temps rise. I’m a side sleeper, so the extra room in the elbows and knees is a huge plus. Plus, I love that it’s part of NEMO’s fully recyclable Endless Promise™ program—it feels good and does good."
We’re all about sleeping outside without sacrificing comfort, and the Forte 35 Sleeping Bag from NEMO helps us do just that. With its Classic Spoon™ shape, it offers extra room at the elbows and knees, so we can shift, curl up, or sprawl without fighting a tight mummy cut. At just over 2 pounds, it’s light enough for backpacking yet warm enough for summer alpine nights or late-season car camping.
This version of the Forte is built with sustainability in mind. It features 100% post-consumer recycled Zerofiber™ 800 synthetic insulation that provides impressive warmth-to-weight, plus a PFAS-free recycled shell and liner. Thermo Gill™ vents give us flexible temperature control, while the Blanket Fold™ draft collar seals in heat when the mercury drops. The entire bag is part of NEMO’s Endless Promise™—designed to be fully recyclable at the end of its life.
