The Ether Light XR eases you to sleep with its 10cm of plush comfort. A long day on the trail deserves a great night’s rest with minimum effort. The Airstream pump integrated into the stuff sack and a high-airflow XPRESS valve make inflation and deflation quick and simple. Lean into the ThermalCore technology which increases insulation while keeping weight and volume low. So toss it in your pannier or backpack and head into the backcountry knowing that your sleep comfort is one less thing to worry about.

Thermal Core insulation with a suspended TRM layer reflects warmth back to the sleeper effectively
