Add an ALPS Mountaineering folding foam mat to the bottom of your sleeping bag to improve the level of comfort. The foldable foam mat is extremely lightweight so you won't be hauling along too much extra weight on your next hike, but will be adding enough padding to make a noticeable difference in how well you sleep at night. The textured foam insulates to keep you warmer and also keeps the mat from sliding around. Each foam mat comes with straps so when you're finished, you can fold it up and easily transport and store it.FeaturesAccordion folding for a small packing sizeComfortable egg crate foam sleeping surfaceLightweight designClosed-cell foam protects and insulates
