Comfort Light Sleeping Mat

An R-value of 3.9 is generally suitable for three-season use, covering spring, summer, and autumn. While it provides solid insulation for chilly nights, it is not designed for deep winter conditions or sub-freezing temperatures.

Unlike traditional horizontal or vertical baffles that can feel like an air mattress, the Air Sprung Cells act like independent pocket springs. This creates a more stable, supportive surface that contours to your body and prevents that bouncy, unstable feeling.

The Airstream Pumpsack is highly recommended over using your lungs. It allows you to inflate the mat quickly without introducing moisture from your breath, which helps prevent internal mold growth and keeps the insulation dry.

The mat features a built-in PillowLock system, which uses hook-and-loop patches to secure a compatible Sea to Summit pillow directly to the mat. This keeps your pillow firmly in place, even if you toss and turn.

The 30D/40D nylon face fabric is designed to be relatively quiet. While no inflatable pad is perfectly silent, this material avoids the loud, crinkly plastic sound common in some other insulated sleeping pads.

It packs down to 9 inches by 4.5 inches, making it a very manageable size for backpacking. It fits easily inside most standard hiking packs without taking up excessive space.
