What Our Gearhead(R) Experts Are Saying: "The Arch Bay 15F Sleeping Bag is my go-to for cold nights. The eco-friendly insulation keeps me warm down to 15degF, and I really like the extra length and width-it's perfect for taller campers.

It's warm, comfortable, and packs up quickly thanks to the Roll Control and Quick Cord features."Built to keep us warm in colder temperatures, the Coleman Arch Bay 15F Sleeping Bag combines eco-conscious materials with premium comfort.
