Sea to Summit Camp Plus Self Inflating Mat

An R-value of 4.3 indicates this mat is well-suited for three-season camping and even mild winter conditions. It provides enough insulation to keep you warm when the ground temperature drops, making it a versatile choice for most camping environments.

The mat uses open-cell foam that expands when you open the valve, drawing air in automatically. While it does most of the work on its own, you may want to add a few breaths of air at the end to reach your preferred firmness.

The PillowLock system is specifically designed to work with Sea to Summit pillows. It uses hook-and-loop patches to keep your pillow from sliding off the mat during the night, so it won't be compatible with standard pillows unless you add your own attachment method.

The 75D polyester is a robust, abrasion-resistant fabric designed to withstand the rigors of campsite use. It is significantly more durable than the ultralight fabrics found on specialized backpacking pads, making it a reliable choice for car camping or basecamp setups.

Delta Core-V technology removes foam in specific areas to reduce weight and bulk without compromising support where you need it most. You get a consistent, cushioned surface that feels stable and supportive throughout the night.

While it is comfortable and packs down reasonably well, it weighs nearly two pounds. It is best suited for car camping or short hikes where weight is less of a concern than overall comfort.
