The 22 Degree Cat's Meow Sleeping Bag is The North Face's lightest and most compressible synthetic bag for backpacking in moist conditions. Its Cyclone construction wraps Heatseeker Pro insulation continuously around the bag to maximize your warmth and maintain a lightweight, compressible design to reduce the weight you're hauling on your back by day. The shaped hood and draft tube help this mummy bag block out cold, whipping gusts, and the pad retainer loops attach to your sleeping pad so you never toss and turn onto the cold, hard ground. Plus, when the sun rises to say hello once more and it's time to move to the next site, the included compression and storage sack easily transport your bag while saving space in your pack.
