NEMO Riff™ Women's Down Sleeping Bag 15

NEMO Riff Women's 15 is a three-season down mummy bag built specifically for female anatomy, using NEMO's Spoon-shaped cut that widens at the knees and elbows so side sleepers can bend their legs without compressing the insulation. Rated to an ISO comfort of -8°C and a limit of -15°C, it fills a cold-shoulder-season niche between typical three-season and true winter bags. The 845 g of 800-fill-power hydrophobic duck down (RDS-certified) sits in mixed box baffles, giving a warmth-to-weight ratio around 10.3 and roughly 97 g of bag weight per degree of comfort - a reasonably efficient trade for a women's-specific cut. At 1460 g total and packing down to 9.5 liters, it sits closer to a lightweight three-season bag than an ultralight one, but the fitted contoured hood, draft collar, draft tube, and Thermo Gill foot vents add comfort and temperature control that minimalist bags skip. It suits users up to 167 cm, and favors hikers who prioritize a snug, anatomically shaped fit and dependable cold-weather range over shaving every last gram.
