Comfort and stability despite minimal weight. Comfortable, reliable, and user-friendly: the Ether Light XR Pro Insulated ASC Mat from Sea to Summit! This technically advanced sleeping mat is the ideal choice for comfort-oriented users with lightweight gear. ASC stands for Air Sprung Cell, an innovative technology featuring dozens of air-filled synthetic springs that provide stable support—regardless of sleeping position.
Innovative processes for maximum functionality. The filling is made from high-quality materials using state-of-the-art laminating and welding techniques. The central technology is called Thermal Core. It incorporates multiple layers of reflective film between the spot-welded seams, which reflect radiant heat back to the sleeper and reduce air movement within the mat. This allows the mat to achieve maximum insulation with minimized weight.
The durability and reliability of the construction are ensured by liquid-extruded TPU lamination and RF welded seams. This makes the Ether Light sleeping mat one of the most comfortable and reliable mats on the market!
Key points at a glance: Consistently reliable materials, innovative construction for exceptional efficiency, and plenty of comfort at a low weight.
