You'll find our Supernova down sleeping bag at both the backyard campout and the backcountry adventure - offering all the compact, lightweight warmth of our popular Cosmic Down, in a roomy shape that accommodates a wide range of body types and sleep positions! Lofty baffles and buttery-soft, recycled fabrics keep you cozy and comfy on colder nights, while an anti-snag zipper design with locking sliders enables you to let off steam when things heat up.
