The Sea to Summit Ultralight Mat is one of the lightest and smallest packable sleeping mats on the market. With an R-value of 1.1, it is designed for use in warm weather.

Instead of a typical divider construction, Sea to Summit feature a spot-welded construction of interconnected chambers that form a large-area matrix. These chambers are "Air Sprung Cells." Air Sprung Cells work like pocket spring mattresses, each chamber deforms independently, allowing the mattress to conform to the shape of the body.

This design makes the Sea To Summit Ultralight Mat more stable, softer, more comfortable, and ensures that you won't bump your hips or knees on the ground while turning in your sleep.
