Description
Experience expansive backcountry comfort.

Roll out the backcountry red carpet with the HiberNest 15°F Down Sleeping Bag, a plush, roomy 650-fill down sleeping bag that packs small and opens into a large quilt. Wide mummy curves provide ample room to stretch out, roll around, and recharge in any position, whether in a tent, hut, or van. For those wanting more room to sprawl, the snag-free zipper wraps entirely down and around the feet, converting the bag into a quilt with extended blanket flaps for maximum comfort. The light, durable ripstop shell with water-shedding DWR and the Down Defender treatment keeps the bag lofty and warm, even in wet or humid conditions.
