Nemo Forte (-6°C / 20F) Synthetic Sleeping Bag Men's 2026 - Fortress/Pelican

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 three sizes — Regular, Regular Wide, and Long — to better accommodate all adventurers.

• Classic Spoon® shape adds room at elbows and knees for versatile comfort.
• Thermo Gill™ vents extend the comfort range with a new multistage zipper system.
