A folding sleep mat made from durable closed-cell polyethylene foam. The mat folds up squarely making it easier for stacking multiple pads in any long-term storage space. It also has permanently attached elastic straps to keep it securely folded during storage. With all the toughness of the U.S. Army ISO-Mat, this packs smaller, faster, and is easier to use and fold out in just a few seconds. For camps, offices, and training facilities, this is a must-have.
