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. Features 4.1 R-Value is warm enough for all but the coldest ground. Three inch thick foam and knitted polyester upper face fabric provides for an amazingly comfortable night’s sleep. Delta Coring removes over 40% of the foam to reduce weight and bulk, without compromising durability. Woven 30D polyester face fabric has been chosen for its light weight and strength. Silicone print prevents your sleeping pad from slipping on the tent floor. Flip-over multi-function valve for fast and easy inflation, deflation and fine-tuning of air pressure. PillowLock system prevents your Sea to Summit Aeros Pillow from slipping. Awards ISPO Award OutdoorGearLab - Top Pick Outdoor Industry Award 2022 SELF Outdoor Award
