For the ultralight enthusiast, the Ultralight™ Self Inflating mat will add the promise of a comfortable sleep to your pack, and not a whole lot of weight or bulk. Delta Core-V™ technology is used to remove small sections of foam without sacrificing comfort. The silicone grip print embossed on the mat ensures you and your sleeping bag stay on the mat. For the ultralight adventurer, pack up is super easy with the patent pending multi function valve that allows you to roll up the mat without air trying to sneak back in as you go. Ideal for gram counters who like to sleep comfortably.
