For those who like to travel light, the Ultralight Self-Inflating Sleeping Mat will add the promise of comfortable sleep to your pack, without significant weight or bulk. While the Delta Core-V technology removes small sections of foam without sacrificing comfort, the embossed silicone grip print ensures you and your sleeping bag stay on the pad. For the ultralight adventurer, pack up is super easy with the patent-pending multi-function valve that allows you to roll it up without air sneaking back in. Ideal for gram counters who like to sleep comfortably.
