Sea to Summit Comfort Light Sleeping Mat

An R-value of 3.8 indicates this mat provides solid insulation for three-season use, meaning it will keep you warm during spring, summer, and autumn camping. It is designed to effectively block cold ground temperatures, making it suitable for most conditions except for deep winter camping.

This technology uses specialized foam coring to remove weight and bulk while strategically increasing insulation in the hip and foot areas. By placing more foam where women typically exert the most pressure, it provides targeted support and warmth without adding unnecessary weight.

Yes, it is a self-inflating mat, meaning the open-cell foam expands to draw air in when you open the valve. While it will do most of the work, you may want to add a few breaths of air at the end to reach your preferred firmness level.

The surface features a silicone print specifically designed to create friction between the mat and your sleeping bag. This significantly reduces the likelihood of sliding off your pad, even if you are camping on slightly uneven ground.

The PillowLock system uses hook-and-loop patches included with the mat to secure a Sea to Summit pillow directly to the top of the pad. This prevents your pillow from migrating away from your head while you sleep, keeping it stable throughout the night.

At 1.47 lbs, this mat balances comfort and weight effectively. While there are lighter options available, this model is designed for those who prioritize a restful night's sleep and warmth over shaving every possible ounce.
