Lightweight Down Sleeping Bags

Made for cool-weather backpacking and camping, the Marmot Hydrogen, Helium, and Xenon bags boast an impressive weight-to-temperature ratio. The outer lining is constructed of Pertex Microlight 20d ripstop nylon that’s coated with DWR, giving the shell a durable, water-repellent finish. Curved baffles prevent the 800-fill goose down from shifting while sleeping, while the Nautilus multi-baffle hood features a built-in drawcord to reduce heat loss. The Xenon sleeping bag features increased insulation in key areas that's designed specifically for women. Finally, the anatomically designed foot box features wrap-around construction, which remains accessible via a full-length two-way zipper so you can better control airflow and temperature.

At checkout, choose the Hydrogen (base price), Hydrogen long (+ $15), Helium (+ $50), Helium long (+ $65), or women's Xenon (+ $90).
