NEMO Equipment Inc. Sonic 15 Sleeping Bag 15 Degree Down

With Thermo Gills ventilation, Nemo's Sonic 15 Sleeping Bag offers a versatile temperature rating suitable for winter desert camping and summer alpine backpacking. Open the Thermo Gills chest zippers and let heat out on warmer evenings, and keep them closed for colder nights. The bag's 850 fill down insulation has the best warmth to weight ratio available, which means you're getting more warmth and less weight. Nemo made the Sonic's shell out of light yet durable ripstop with a DWR treatment to shed moisture, and there's a waterproof, breathable Osmo DT membrane at the footbox for extra protection. The Sonic also features an adjustable hood with a draft collar to keep the cold out, a full length zipper, and stuff and storage sacks.
