Keep your head and pillow off the cold ground when you lie down to sleep in the Montauk 40°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 40°F outside. The Comfort Cuff design makes sure you only have soft fabric around your face while you sleep. Thanks to the Zip Plow 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.
