Sonic 15 Sleeping Bag (850 Down)

The Sonic Sleeping Bag from Nemo is the winner of a 2015 Backpacker magazine Editor's Choice Award, being praised for being the only bag you really need from 0deg to 40degF. Adjustable Thermo Gills allow you to control the internal temperature of the bag without letting in cold drafts, extending your comfort range by 20degF or more. Stretch construction at the knees helps maintain bag shape, thermal efficiency and loft, while offering enhanced volume so you can sleep on your side with your knees bent.
