Based on our best-selling Cloud sleeping bag, the Night Cap 20 is a more affordable, responsibly-made version of its award-winning sibling for off-the-grid adventure seekers who need a better insurance policy in wet weather while still packing down to a backpack-friendly size. Made with 100% recycled synthetic insulation from water bottles and wrapped in a recycled, post-industrial fabric shell, the Night Cap 20 integrates a zipperless, oversized comforter and a sleeping pad sleeve for a bed system that’s as cozy as home and offers more freedom for stretching out than traditional mummy bags. Loads of features ensure warm air doesn’t escape, like insulated shoulder pockets and baffled construction to keep the high-loft insulation from forming cold spots, but hot sleepers rest assure: the self-sealing foot vent provides the perfect environment, no matter how cool you like it.
