Sea to Summit Ether Light XT Extreme Insulated Sleeping Mat

Redefining the definition of a good night's sleep! 

The redesigned and upgraded Ether Light XT Extreme Insulated Sleeping Mat has a new comfort level for improved sleep quality wherever you are. With an R-value of over 6, the Extreme mat has a few small changes that have made a big difference. 

So what's the difference? Air sprung cells make up the core technology of the sleep mat range. Unlike the typical baffled mat construction that a lot of mats use, the Ether Light XT Extreme Insulated Sleeping Mat uses air-sprung cells that create larger pockets of air, which operates similar to a pocket spring mattress. Each air-sprung cell deforms independently and allows the mat to conform to your body, providing ultimate support and comfort by evenly dispersing pressure across the mat's surface.   

Offering more stability than thinner mattresses, its lightweight and the thickest full-size air-sprung cell mat of the Sea to Summit range. Designed for four seasons of comfort and insulated for warmth and a better nights sleep. The mat is only 10cm thick and has an incredibly low weight, however, it has been refined for a superior night's sleep. Dual-density layers of THERMOLITE insulation fill the air-sprung cells to boost warmth and prevent convective heat transfer whilst maintaining its lightweight and packability. 

The mat is also fitted with a multifunctional valve for easy inflation and deflation. Sea to Summit knows just how frustrating and time-consuming inflating and deflating a mattress can be, so they’ve developed their own patent-pending multi-function valve with an integrated inflate port with a one-way valve to prevent air loss before you seal the valve. A rapid air dump deflate port and a fine tune button to adjust the air level for optimum comfort.     

Offering an exceptional comfort-to-weight ratio, the extra height of the mat lets the hips sink deeper into it without touching the ground. The extra thick and exceptionally warm Ether Light XT Extreme Insulated Sleeping Mat has a new comfort level for improved sleep quality wherever you are.
