Sea to Summit Comfort Plus XT Insul. Air Mat Rectang. Reg.Wide red

A dual-chamber, four-season mat engineered for side sleepers who need genuine insulation and pressure relief on uneven ground.

The Sea to Summit Comfort Plus XT Insulated Rectangular Air Mat uses a two-layer Air Sprung Cell (ASC) construction, with each chamber inflated independently via a multi-function valve. The wider-than-standard 64 cm profile allows hips to sink without ground contact, while Exkin Platinum reflective fabric and THERMOLITE HL-1 fiberfill insulation combine for an R-value of 4.7 — suitable across all four seasons.
