For fast-and-light missions where every gram counts, the Sea to Summit Ultralight XR Insulated Air Sleeping Mat – Regular delivers impressive stability, warmth, and packability for backpacking, bikepacking, and thru-hiking. It uses 151 Air Sprung Cells to contour to your body and reduce pressure points, while the wider profile suits side sleepers and anyone who rolls around overnight. ThermalCore insulation reflects body heat to boost warmth and reduce packed size, and the hybrid 30/40D nylon with Ultrafresh-treated TPU laminate is built for proven durability. Inflation, adjustment, and rapid deflation are simple thanks to the XPRESS valve and the integrated Airstream pump sack.
