Nemo | Forte™ Endless Promise® Men's Synthetic Sleeping Bag 20℉

The inaugural product that launched our Endless Promise®  collection, Forte is a beloved 3-season bag for the backcountry. Featuring high-performance synthetic fill and the crowd-favorite Classic Spoon® shape, it's a standout in sustainability, performance, and comfort.

NEMO’s Classic Spoon shape continues to be a game changer for side sleepers, offering more room at the knees and shoulders for a less-constricted feel that’s still compact. Equipped with two-stage Thermo Gill™ zippered vents, Forte offers an extended usable temperature range that can be fine-tuned for comfort from within. Additional temperature regulation can be achieved by strategically arranging the cozy Blanket Fold™ draft collar; tuck it in for greater warmth and leave unfolded to release any excess heat.

Made with a suite of recycled fabrics and filled with 100% recycled Zerofiber™ 800 synthetic fill, Forte continues to exemplify NEMO’s commitment to reducing resource consumption and keeping our gear out of the landfill. Manufactured from a single type of material, this sleeping bag is fully recyclable at the end of its life — just send it back to NEMO, and we’ll handle the rest.

Packable, warm even when wet, and armed with NEMO’s top sleeping bag features, Forte is now offered in a Regular Wide and Long Wide.
