Sea to Summit Comfort Light Self-Inflating Mat

An R-value of 2.7 indicates this mat is best suited for three-season use, providing enough insulation to keep you warm during spring, summer, and early autumn nights. It is designed to block the cold ground from sapping your body heat, but it may not be sufficient for freezing winter conditions.

Delta Core technology removes foam from non-essential areas to reduce weight and bulk. While this makes the mat lighter and more packable, you will still feel a consistent, supportive surface across the areas where your body needs it most.

With a thickness of 2.0 inches, this mat offers a decent buffer against the ground. While it provides more support than a closed-cell foam pad, side sleepers who prefer a very plush feel might find it slightly thinner than specialized inflatable air pads.

The valve features a one-way design that allows you to inflate the mat easily without air escaping between breaths. It also includes a secondary setting that opens the valve completely for rapid deflation, making it much faster to roll up and pack away.

No, this specific model does not include a repair kit. It is always a good idea to purchase a universal field repair kit separately to handle any unexpected punctures while you are in the backcountry.
