The hybrid shape of the Coleman Dunns Creek 20 Sleeping Bag gives you all the added warmth of a mummy and the extra space of a rectangular bag, perfect for when the temperature dips down to 20 degrees. When things cool off, lightweight Coletherm hollow polyester insulation helps to retain heat all night long. 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 keep small things, such as gloves or a flashlight, in the interior tuck pocket. Packing up is made 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.
