Sea to Summit Ultralight XR Insulated Mat yellow (various sizes)

Three-season insulated air mat built for backpackers and outdoor professionals who need packable warmth without compromising on sleep quality.

The Sea to Summit Ultralight XR Insulated Mat uses 151 Air Sprung Cells to contour to the body and reduce pressure points across the sleeping surface. ThermalCore insulation reflects body heat to deliver an R-value of 3.6, making it suitable for shoulder-season conditions. The 64 cm width accommodates side sleepers, and the integrated Airstream pump sack with XPRESS multi-function valve handles inflation, pressure adjustment, and deflation without a separate pump.
