The Camp Quilt Sleep Set is yet another innovation from Kodiak Canvas. The quilts function together as a zipper less alternative to a sleeping bag. The smaller Twin XL-sized quilt goes on the bottom. The larger top quilt has space to wrap up in and get comfy. Use it as bedding for your RV or cabin, as an over blanket to boost the warmth of your sleeping bag, or take it on a picnic. Made with the same materials as our top-of-the-line Z Top sleeping bags. It has a rugged, water-resistant, canvas shell and a posh 100% cotton flannel liner. The efficient Factor-4™ insulation is a hollow fiber polyester that is light, fluffy, and very warm. An easy carry, canvas, stuff bag is included. Bag the restrictive sleeping bag. Ditch the zippers.
