Big Agnes Storm King 0 Sleeping Bag

Big Agnes Storm King 0 Sleeping Bag


The Big Agnes Storm King 0 Down Sleeping Bag offers warmth, compressibility and the Big Agnes System bag design. Big Agnes redesigned their Classic Series bags to combine a roomier semi-rectangular shape with a narrower integrated pad sleeve to allow you to roll more freely and sleep more comfortably. The 650 fill Downtek water resistant down repels water to maintain loft and insulation value while Insotect flow construction ensures uniform insulation coverage and eliminates cold spots. The Free Range Hood Design and low profile cord lock allow you unrestricted movement while staying hooded, but also give you the ability to release the hood with one hand. Additional features include a tapered vaulted foot box to avoid cold pockets and a stretch fabric panel pillow pocket.
