The Ether Light XT sleeping mat uses looped baffles of Thermolite® insulation for an incredibly warm and comfortable sleep, even in a cold climate. The women’s specific shape is wider at the hip and narrower at the shoulder. The Air Sprung Cell construction offers a generous 10 cm thickness inside a very light and noticeably quiet 30/40D nylon fabric, Exkin Platinum®. Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground Ether Light XT Women's Insulated Sleeping Mat
