Product details: Sea To Summit Ether Light XT - Regular Insulation Mat Shadow

The Sea To Summit Ether Light XT is a lightweight, yet thick, super quiet sleeping mat with full-surface Air Sprung Cells. With an R-value of 3.2, it is sufficient for use from late spring to early autumn.

The Air Sprung Cells adapt optimally to the shape of the body and provide extra comfort even under uneven load. This makes the Sea to Summit Ether Light XT perfect for side sleepers.

Sea To Summit has developed the 30/40D outer material to create a perfect balance between weight and resilience. The 40D longitudinal thread that forms the frame of the fabric provides resilience, while the 30D transverse thread keeps the overall weight of the fabric as low as possible and gives the fabric of the Ether Light XT Insulation Mat a pattern = rough surface.


• 3.2 R-Value is sufficient for late spring to early fall use.
• At four inches thick, Ether Light XT Air Sprung Cells provides a plush sleeping experience.
• Exkin Platinum insulation reflects your radiant heat back to you, Thermolite insulation prevents convective heat loss.
• Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable.
• Quick and easy inflation, deflation and adjustment is made possible by the multi-function valve and supplied Airstream Pump/stuff sack.
• Anti-microbial treatment added to the TPU lamination formula prevents internal mold growth.
• PillowLock system prevents your Sea to Summit Aeros Pillow from slipping.
• Comes with a stuff sack which doubles as a pump, a repair kit with six self-adhesive patches and a spare valve insert.
