Lightweight shell material, and premium 800-fill goose down allow us to craft a warm-but-featherweight sleeping bag—the Wicked Light. We realize, however, that skimping on details will only result in a poor night's rest, so we dial the Wicked Light out with removable Pad Locks, continuous baffle construction, and Snag Free Zipper Tracks. According to our research, cramped, overheated feet result in disturbed sleep, and Foot Box Venting allows you to regulate temps in the bottom of your bag. At just over a pound, the Wicked Light offers an unbeatable warmth-to-weight ratio…and a great night's rest.
