Keep your head and pillow off the cold ground when you lie down to sleep in the Coleman? Montauk? 40 F Big and Tall Adult 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 40 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.
