Ether light XR Insulated ASC Mat

The Ether Light XR is the thickest and warmest sleeping mat in our Ultra Light range, due to using new insulation, Thermal Core®. The Air Sprung Cells still provide four inches of stability and comfort, while Thermal Core® insulation prevents convective heat loss and internal air movement. This results in true four-season performance perfect for backpacking, light weight camping, bikepacking and sea kayaking.
