After a long day on the trail, the Ether Light XR eases you to sleep with its 10cm of Air Sprung Cell plush comfort. Getting your mat ready for the night is easy too - the Airstream pump integrated into the stuff sack and a high-airflow XPRESS valve make inflation quick and simple. ThermalCore technology provides a greater level of insulation than prior models, while keeping weight and volume low. Pop an Ether Light XR in your pannier or backpack and head into the backcountry knowing that your sleep comfort is one less thing to worry about.
