Sea to Summit, the globally recognized brand of award-winning adventure gear, introduces their new Ether Light XR Insulated Air Pads—a new generation of ultralight sleep systems designed for maximum warmth, minimal weight, and year-round adventure.
At the core of the Ether Light XR series is Thermal Core Insulation, a breakthrough design that suspends a reflective film inside the mat to trap radiant body heat and minimize internal air movement. This advanced insulation boosts thermal efficiency without adding bulk, delivering serious cold-weather performance in an ultralight package. Combined with Air Sprung CellTM technology, liquid-extruded TPU lamination, and RF welds, the result is a mat that offers plush, reliable comfort in any terrain.
With an ASTM-tested R-Value of 4.1, 10cm of cushion, and weighing in at just 470 grams, the Ether Light XR Pro is ideal for thru-hikes, alpine treks, and minimalist backcountry missions.
Enhanced weld strength and minimized curvature between weld points reduces weight while increasing longevity. The mat features Sea to Summit’s XPRESSTM valve and integrated AirstreamTM pump sack for fast, intuitive setup and precise inflation control.
For winter adventures, the Ether Light XR Pro delivers expedition-grade insulation with a staggering R-Value of 7.4, the highest ever from Sea to Summit. Engineered with multiple suspended thermal layers, the XR Pro is built for alpine routes, ski touring, and extreme cold. Despite its warmth, it weighs only 560 grams, making it 22% lighter and a 79% smaller pack volume than the previous model. With double the weld strength and a 10cm profile, the XR Pro sets a new standard for high-performance winter sleeping pads.
“With the launch of the Ether Light XR and XR Pro, we’re not just evolving our technology—we’re raising the bar for comfort and performance in the backcountry,” commented Sea to Summit Brand Manager, Margaux Maertens. “Whether you’re deep into a thru-hike or setting up camp in snowy alpine conditions, the XR and XR Pro deliver warmth and reliability without compromise.”
Both models reinforce Sea to Summit’s commitment to pushing technical boundaries while supporting every adventurer’s pursuit of better nights under the stars.
The Ether Light XR and XR Pro are available now at https://seatosummit.com/ and through select retailers.
