Sea to Summit Comfort Light Sleeping Mat

The mat uses a dual-layer design in the torso area for extra support and stability, while the head and leg sections use a single layer to save weight. This hybrid approach ensures you get cushioning where you need it most without adding unnecessary bulk to your pack.

Yes, an R-value of 3.7 is well-suited for three-season use, providing sufficient insulation for spring, summer, and autumn conditions. It effectively reflects body heat and blocks cold ground transfer, keeping you comfortable in varied temperatures.

The mat includes an Airstream Pump sack, which allows you to inflate the pad quickly using ambient air rather than your breath. This method prevents moisture buildup inside the mat, which helps maintain the integrity of the insulation and prevents internal mold growth.

This mat features a Pillow Lock system, which uses hook-and-loop patches to secure compatible Sea to Summit pillows directly to the pad. If you use a different brand, you may experience some sliding, though the textured surface helps reduce movement.

The mat comes with a dedicated repair kit designed for field maintenance. It includes adhesive patches that allow you to seal small punctures quickly, ensuring you can continue your trip without losing sleep.

When deflated and rolled, the mat packs down to approximately 9.45 inches in length and 4.72 inches in diameter. It is designed to be compact enough for backpacking, fitting easily inside or strapped to the outside of most standard hiking packs.
