Add an ALPS Mountaineering 375 Foam Sleeping Pad Mat to the bottom of your sleeping bag to improve the level of comfort. The foam mats are all 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 roll it up and easily transport and store it.Specifications and Features: Very lightweight Protects and insulates Dense closed-cell textured foam Easily rolls up for packing
