The Comfort Plus Self-Inflating Sleeping Mat is pure camping luxury. This is a plush, three inch thick, light and easy to use option for anyone looking for maximum comfort. The Delta Core technology reduces the foam's weight and bulk without compromising comfort. A lightweight but luxurious 30D stretch knit fabric is used on the top surface and each pad is embossed with a non-slip grip print to keep the mat from slipping. And we've literally put a twist on our multi-function valve to ensure super-fast deflation, without fighting re-inflation, as you roll it up.
