Product Description
FOUR-SEASON INSULATED AIR SLEEPING MAT WITH 10 CM AIR SPRUNG CELL COMFORT, 7.4 R-VALUE, THERMALCORE INSULATION, XPRESS VALVE AND INTEGRATED AIRSTREAM PUMP SACK
The Sea to Summit Ether Light XR Pro Insulated Air Sleeping Mat is built for winter camping, mountaineering and cold-weather backpacking where warmth, comfort and packability all matter. It delivers serious insulation and plush support while reducing packed size and weight compared to previous Ether Light models.
ThermalCore insulation uses multiple TRM layers to reflect infrared energy back toward the sleeper, increasing insulation without unnecessary bulk. With an ASTM-tested R-value of 7.4, the Ether Light XR Pro is ready for true four-season use and cold ground conditions.
Air Sprung Cell construction provides 10 cm of plush, stable comfort, helping the mat contour to your body in any sleeping position. Whether you sleep on your side, back or shift through the night, the supportive air cell structure helps reduce pressure points and improve sleep quality outdoors.
Inflation, fine-tuning and deflation are quick thanks to the XPRESS valve and integrated Airstream pump sack built into the stuff sack. Increased weld strength improves long-term durability, while PillowLock patches help keep compatible Sea to Summit pillows secure through the night.
Available in Small, Regular, Regular Rectangular Wide, Large and Large Rectangular models, the Ether Light XR Pro gives cold-weather adventurers a warmer, more compact and more comfortable sleep system for serious outdoor use.
