A beloved 3-season bag for the backcountry, this 100% recyclable synthetic sleeping bag is also our first Endless Promise product, making it a standout in sustainability as well as comfort and performance. Forte Endless Promise'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. The upgraded Thermo Gill design features a new multistage zipper system that dramatically increases the usable temperature range of the bag and allows for fine-tuning of comfort from within. Forte EP uses 100% recycled insulation and fabrics and is carefully designed so no waste is left on the cutting room floor — case in point: the full-length draft tube is filled with reclaimed fiber leftovers. The bag itself is filled with Primaloft lightweight, ultra-lofty, and supremely resilient insulation, which features 80% post-consumer recycled content. This synthetic fill packs down small, maintains its loft longer, and provides superior warmth even when wet. Equally important to its use of recycled materials is the fact that this entire bag can be fully recycled at the end of its life when returned to NEMO. Cozy details like the Blanket Fold draft collar and integrated Pillow Pocket pair with buttery-soft fabrics to keep comfort at the forefront. You might even say that comfort is this bag's... forte.
