Etherlight XR Insulated Air Mat

Sea to Summit Ether Light XR Insulated Air Sleeping Mat

The Sea to Summit Ether Light XR Insulated Air Sleeping Mat is a lightweight and comfortable inflatable sleeping mat for backpacking, thru-hiking, and bikepacking. With a 10 cm thick Air Sprung Cell construction, it provides soft, stable comfort regardless of sleeping position, while the ThermalCore insulation reflects heat back towards the body. The ASTM-tested R-value of 4.1 makes the sleeping mat suitable for extended three-season use and cooler nights where the ground chill starts to become noticeable. The integrated Airstream pump in the stuff sack and the XPRESS valve make inflation, adjustment, and deflation quick and easy.
