Snap out of the cold and into the Cloudbreak for a great night's sleep. Rated to 20°F, you can get cozy in the cold and still be warm as a wombat. The body-mapped insulation is specifically designed to bring maximum warmth and efficiency to areas where it's needed most, while reducing overall weight and bulk. Brilliant! Throw in a 3D hood construction, full length zipper and a face muff and you've got a serious contender in the fight against cold. Weighing in at less than 3 pounds, you'll be hard pressed to find a lighter synthetic bag for the warmth and the quality. Break into the Cloudbreak, and fear the cold no longer!
