Built for serious cold-weather missions, the Sea to Summit Ether Light XR Pro Insulated Air Sleeping Mat – Regular delivers four-season warmth without sacrificing packability. ThermalCore insulation uses multiple quiet TRM layers to reflect warmth back to you and reduce internal air movement, helping you stay comfortable in winter camping and alpine conditions. Air Sprung Cell construction provides 10 cm of stable, plush support for side, back, and restless sleepers. Setup is fast and clean thanks to the XPRESS valve and the Airstream pump integrated into the included stuff sack, making this mat a dependable choice for cold-weather backpacking.
