Spread out for the night and get comfortable. Extra comfortable. The rectangular and roomy Callisto 20 is designed to take on multiple seasons and offers big time coziness with super soft CloudLoft™ insulation. It also offers the versatility to snuggle up together as a couple. Just zip two Callisto bags together using the full-length zippers and you’ll have a doublewide bed in the wild in a flash. Or, if things heat up, unzip your bag and use it as a blanket instead. Sleep tight and move free.
