NEMO Riff™ Men's Down Sleeping Bag 15

The NEMO Riff 15 is a men's bag in NEMO's signature Spoon shape, which blends a mummy cut with extra room at the knees and elbows — a design aimed at side sleepers who find a traditional narrow mummy bag restrictive to turn in. A -2°C comfort rating and -9°C limit (EN ISO 23537) put it in cooler three-season territory. Filled with 585 g of 800 fill-power hydrophobic, RDS-certified duck down, it weighs 1161 g total — heavier than mummy bags in a similar temperature class, which is the tradeoff for the roomier cut. Horizontally oriented box baffles keep the down from shifting, and a full-length, two-way zipper on the left side allows venting or coupling two bags together. A contoured hood, draft collar, footbox ventilation, and an internal pocket round out the feature set. The 20D shell and 30D liner, both DWR-treated nylon, resist moisture from tent-interior condensation. It packs to 45 × 23 cm (6.2 liters) and suits trips where side-sleeping comfort and room take priority over shaving every last gram.
