Are you a tosser, a turner, a flipper or a flopper? All good…the Tuck has the room for any of your moves. The Tuck 20 mummy bag packs down into a compact little package so you don’t have to give up your creature comforts. Built with silky soft polyester for durability, and soft touch premium insulation for warmth, we’ve upped the amount of insulation in the hood to give you a built-in pillow, and keep your toes toasty. And if in the middle of the night you feel too warm, a convenient foot zipper lets you find your happy place.
