Kelty Supernova Down Sleeping Bag – 40°F Regular, Compact + Roomy Fit, Recycled Shell

Overview

Meet the Kelty Supernova down sleeping bag—an easy-to-carry option that blends compactness with a roomier cut. Building on the brand’s Cosmic lineage, it adds loftier baffles and a buttery-soft fabric that feels inviting on cool nights. This design supports easy movement between sleeping positions while remaining light enough for a backpacking-ready setup. The anti-snag zipper with locking sliders gives you smooth venting and adjustable warmth without snagging on fabric or gear.

Inside, the bag uses 550-fill power down for reliable loft and warmth, delivering a cushioned, breathable feel. The down is gray duck and RDS certified, while Kelty’s recycled materials program contributes to a more sustainable shell and liner. The result is a warmer nights’ rest with a lighter environmental footprint, all while keeping the total weight manageable for everyday adventures.
