Stay nice and warm while camping with the Patagonia Insulated Down Sleeping Bag. Featuring a ripstop nylon Pertex Quantum exterior, this sleeping bag functions in temperatures as low as 19F/-7C. Ideal for extreme adventurers, the Down Sleeping Bag also has a Houdini nylon fabric interior. With this, it dries quickly and easily while remaining super soft against your skin. In addition to these fabrics, the Down Sleeping Bag uses an 850-fill-power goose down. No matter the weather and extremely low temperatures, you can cozy up inside to stay nice and warm. Finally, the top features a low-profile hood to keep you truly warm from head to toe. The Down Sleeping Bag comes in your choice of blue or orange to match the rest of your gear.
