Kelty Supernova Down Sleeping Bag 40°F – Compact, Roomy, Recycled Shell (Long)

The Kelty Supernova down sleeping bag carves a space between casual campsite evenings and backcountry nights. It combines the compact, lightweight warmth you expect with a roomier cut designed to accommodate a wide range of body types and sleep positions. Lofty down loft and soft fabric create a cozy feel when the air turns cool, while a practical anti-snag zipper with locking sliders gives you breathable control without fuss. Best of all, it packs down quickly into the included stuff sack, making it a smart companion for quick trips or longer treks where weight and space matter.
