The Enigma Sleeping Quilt is EE's lightest and most minimalist sleeping quilt. It is the perfect ultralight quilt for those who always get cold feet. Exceptionally warm and extraordinarily light, the Enigma offers upper body freedom of movement, while providing structure for your feet. The Enigma doesn't have a zipper or a built in hood, saving even more space and weight in your pack. The Enigma is a sleeping quilt, not a sleeping bag, which means it's designed to be used with a sleeping pad to provide insulation underneath you, between you and the ground.
