Sine Sleeping Bag: 20F Down

Kelty's Sine 20 Sleeping Bag comes with the protection and weight-saving mummy shape that backpackers look for, and a unique Arc Zipper System lets you sleep like you usually do at home. There are two zippers that run diagonally across the front of the bag so your arms and legs can splay while you sleep. This sleeping bag also boasts Kelty's most protective and lofty insulation. DriDown keeps the bag's weight down to two pounds, and it maintains its lofty warmth in moisture-riddled environments. Kelty also designed this bag with an adjustable hood and ergonomic toebox to keep you snug in cold weather, and the built-in pillow acccommodates puffy jackets for extra comfort.
