SFC Forty Winks Sleeping Bag: 20 Degree Synthetic

Nothing ruins a night more than being cold while tossing, and turning, but Sierra Designs' SFC Forty Winks 20 Degree Synthetic Sleeping Bag won't let those things bother you. After all, it was originally designed for military use, so you know that it works. It's been packed full of Climashield Combat synthetic insulation, which has been treated with Polarguard 3D to ensure that it stays lofty and warm, while the tough Epic nylon shell prevents the bag from ripping if you're sleeping on the ground. The fabric also uses Flex technology and a shingled construction for flexibility, so you can sleep comfortably on your side, back, or stomach.

If you need to sit up and work while you're in your bag, the Forty Winks' dual half-length zippers will let you do so without exposing your whole self to the cold. Draft tubes along each track prevent cold air from creeping in, and the NightCap drawcord hood provides snug and comfortable protection for your brain bucket. Final touches include the noiseless zipper pulls, which won't jingle every time you move, and the integrated pad locks designed to keep you from rolling off your pad in the middle of the night.
