Ether Light XR PRO is the warmest sleeping mat we make. New and innovative Thermal Core® insulation allows the XR PRO to reach an R-value of 7.4 yet is small and light enough to carry in a rucksack. The Air Sprung Cells still provide four inches of stability and comfort regardless of sleeping position, while Thermal Core® insulation prevents convective heat loss and internal air movement. This results in outstanding comfort and warmth in very worst of cold weather conditions.
