Keep your head and pillow off the cold ground when you lie down to sleep in the Coleman? Montauk? 20?F Big and Tall Sleeping Bag with a contoured top. Lightweight Coletherm? hollow polyester insulation and the Thermolock? draft tube along the zipper helps keep body heat from escaping so you stay warm even when it's 20?F outside. The Comfort Cuff? design makes sure you only have soft fabric around your face while you sleep. Thanks to the ZipPlow? zipper, you'll get snag-free opening and closing every time. You can stash small items, such as gloves or a flashlight, in the interior tuck pocket. Packing up is easy with the Roll Control? system to keep your bag straight while rolling and the no-tie Quick Cord? system to keep things cinched tight for storing inside the included stuff sack.
