No subject to promotional offersThe Ether Light XR Insulated Rectangular is an inflatable mattress from the brand Sea to Summit, ideal for bivouac use and designed for 3-season use thanks to its R-Value of 4.1.
This mattress stands out due to its innovative Delta Core™ construction, which optimises heat retention where it is needed while reducing the overall weight by about 20%. With its 10 cm thickness, it offers exceptional comfort and good insulation against ground cold. Its upper surface is made of 30D stretch fabric, providing a soft and pleasant feel, while the underside in 75D polyester with TPU lamination ensures excellent robustness and durability.
The Ether Light XR Insulated also features the Pillow Lock™ system to which you can attach an Aeros™ pillow for perfect support throughout the night. Its multifunction valve makes inflation and deflation easy, and the included Airstream bag also serves as a pump sack for effortless inflation. Ergonomic and optimised, this mattress is an ultra-light and compact companion for your outdoor adventures all year round.
