Sea to Summit Ether Light XR Insulated Air Sleeping Mat
The Ether Light XR Insulated Air Sleeping Mat from Sea to Summit offers an unparalleled sleeping experience for outdoorenthusiasts who value comfort and functionality. Thanks to the innovative Air Sprung Cell technology, which consists of numerous air-filled 'springs', the mat offers exceptional stability and support. This construction ensures that the mat adapts perfectly to the body and thus enables a restful sleep.
Particularly noteworthy is the Thermal Core insulation, which is equipped with a reflective foil. This foil reflects radiant heat back to the sleeper and minimizes air movement within the mat, providing excellent insulation. With an impressive R value of 4.5 and a thickness of 10 cm, the mat offers optimum protection against ground cold even in colder temperatures.
Made from durable 30-/40D-nylon and with liquid-extruded TPU-lamination, the Ether Light XR promises durability and reliability. The reflective properties of the mat also prevent convective heat transfer, which further increases sleeping comfort. The mat comes with a practical stuff sack that contains an integrated pump sack and a patented X-Press valve that enables quick inflation and adjustment. A repair kit is included for unexpected repairs on the go

Technologies and manufacturing processes
Thermal Core Insulation
Thermal Core insulation uses one or more layers of TRM material to return heat to the sleeper. The TRM layers reduce internal air movement, and the smaller punched holes compared to previous models reduce this even further. The result is a significant increase in R-value and real insulation performance while reducing weight and pack volume.ASTM F3340 R-Value Testing
To make sure you are warm when you sleep (especially if the floor is colder), it is important to know how well your sleeping mat resists heat loss into the floor. This resistance is known as the R-value. A lab-tested R-value is the only way to measure resistance to heat lossXPRESS Valve
Sea to Summit has developed the XPRESS valve to make inflation, deflation and adjustment of its air mats quicker and easier than conventional air mats. The valve integrates a one-way inflation port, a quick deflation port and a fine adjustment knob into a single, low-profile unit. The XPRESS valve fits into the nozzle of the Airstream pump, which is integrated into the pack sack supplied with your Sea to Summit Air Sprung Cell sleeping mat ("Pro tip: Turn the inflation bag of the sleeping mat pump over to expose a nozzle that is perfect for the Mini-XPRESS valve of an Aeros Pillow)INTEGRATED AIRSTREAM
The Airstream Pump Bag is Sea to Summit's high volume mattress pump, which we have now integrated into the pack sack of every Air Sprung Cell mat.PILLOW LOCK SYSTEM
The Pillow Lock System consists of self-adhesive Velcro patches that are supplied with all Sea to Summit Aeros Pillows (from spring 2026). Attached to your sleeping mat, these patches secure your pillow and prevent it from slipping. All Sea to Summit Pillows (from spring 2019) are compatible with this system.
