Crafted for women who desire a perfect night's sleep!

Women's and men's bodies are vastly different- so it's only natural to create mattresses that support's those differences.

Sea to Summit has redefined the definition of a good nights sleep and made small changes that have made a big difference. Alongside that, they engineered the mat to have an anatomical design that supports the shape and sleeping trends of women.

The combination of these two things have created the most lightweight and thickest sleeping mat in the Sea to Summit range, and probably the most comfortable, but we’ll let you be the judge of that.

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 light weight 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, it’s perfect for women who are naturally more intuitively side sleepers because the air pockets allow for movement. The extra height of the mat lets the hips sink deeper into it without touching the ground. The women-specific mats are also wider from the hip to the knee and narrower at the shoulder, and an additional thicker THERMOLITE layer and a Delta Core profile have been added to create a warmer core to ensure a more regulated body temperature.

The extra thick and exceptionally warmEther Light XT Extreme Insulated Women's Sleeping Mat has a new comfort level for improved sleep quality wherever you are.
