From ultra-light, fast hikes above the tree line to relaxed hut-to-hut trekking, the award-winning Air Sprung Cell sleeping mats offer airy comfort even on uncomfortable sleeping surfaces. The 10 cm thickness of the mat allows the hips to sink deeper without touching the ground, making the Ether Light XT perfect for side sleepers. The Air Sprung Cells adapt optimally to the body's shape and provide exceptional comfort even under uneven loads. The Ether Light features a single-layer design. Numerous interconnected TPU chambers create large air cores, sealed at the top and bottom with Air Sprung Cell point welding. These generously interconnected chambers position the upper and lower layers further apart, resulting in less material and weight. The extra-thick Air Sprung Cells are made from lightweight, quiet, and slip-resistant 30/40D nylon fabric. An ultra-fresh antimicrobial treatment of the TPU reduces the risk of mold formation. The Air Sprung Cells ensure a comfortable sleep. The multifunctional valve allows for easy handling. With the integrated PillowLock, Sea to Summit Aeros pillows can be securely attached to the sleeping mat.
