The Nemo Sonic 0 Sleeping Bag is a zero degree sleeping bag for cold weather sleeps in the mountains. Fish aren't the only ones with gills these days, as this bag has Thermo Gills™, which helps regulate the internal temperature. Little warm? Open 'em up. Little cold, keep 'em closed. The 850 fill power down delivers the heat while compressing down for space saving in your pack.
