Sea to Summit Comfort Light Sleeping Mat

An R-Value of 3.1 indicates this mat is suitable for three-season use, meaning it provides sufficient insulation for spring, summer, and autumn camping. It will keep you comfortable in temperatures down to roughly freezing, but it is not intended for deep winter or sub-zero conditions.

The mat uses open-cell foam that expands when you open the valve, drawing air in automatically. While it will inflate most of the way on its own, you can easily top it off with a few breaths or a pump to reach your preferred firmness.

No, the surface features an anti-slip silicone print specifically designed to grip your sleeping bag. This keeps both you and your bag securely centered on the mat, even if you are sleeping on a slight incline.

Delta Core technology removes 40% of the foam volume without sacrificing support or warmth. This significantly reduces the packed size and weight of the mat, making it much easier to carry in a backpack compared to traditional foam pads.

Yes, this mat is compatible with the Sea to Summit PillowLock system. It uses hook-and-loop patches to secure your pillow directly to the mat, preventing it from sliding away while you sleep.

The mat is constructed with 30D polyester, which balances durability with weight savings. While it is tough enough for standard backpacking use, you should always clear your campsite of sharp sticks or rocks before laying it down to protect the fabric.
