The NEMO Forte Endless Promise Women's 20 is the women's version of the Classic Spoon-shaped synthetic bag, cut for a shorter frame (up to 168 cm) with different proportions through the shoulders and hips — a 152 cm shoulder girth and 142 cm hip girth give extra room exactly where women's bags typically need it, unlike a narrow mummy cut. A comfort rating of -6°C and limit of -13°C, tested to ISO 23537, put it in colder 3-season, borderline winter territory.
That warmth comes from a generous 1430 g of Zerofiber 800 fill, bringing total bag weight to 1650 g — heavy for a synthetic bag, but the trade-off is insulation that holds up even when damp, where synthetic fill outperforms down. The shell and liner are 20D recycled polyester with a DWR finish, and a contoured hood, draft collar, and internal pocket round out the feature set.
Bluesign-certified, PFC-free, and designed for full recyclability, this bag suits hikers up to 168 cm tall planning colder-weather trips who want the reliability synthetic insulation offers over down.
