Sea to Summit Comfort Plus XT Insulated Air Mat Rectangular Large red

A four-season air mat engineered for side sleepers and demanding terrain, with dual-layer pressure control and combined radiant and convective insulation.

The Sea to Summit Comfort Plus XT Insulated Rectangular Air Mat uses a dual-chamber Air Sprung Cell (ASC) construction where the base and top layers inflate independently. The base can be held at high pressure for stability on uneven ground while the top layer is adjusted for personal comfort. At 65 cm wide and 8 cm thick, it gives side sleepers enough depth for hips to sink without ground contact. Exkin Platinum metalized fabric and THERMOLITE hollow-core fiberfill work together to achieve an R-value of 4.7.
