Product details: Sea To Summit Ether Light XT Extreme - Regular Insulation Mat Black / Orange

With an R-value over 6, the 10 cm thick Ether Light XT Extreme sleeping pad from Sea To Summit redefines lightweight sleeping comfort for winter adventures around the globe. The Air Sprung Cell technology is the reason why you sleep better on these mats.

Each Air Sprung Cell deforms independently, allowing the mat to mould to your body shape. This provides more comfort by distributing pressure more evenly over the surface of the mat.

For the extra thick (XT) Ether Light design, StS use many TPU loops to connect the top and bottom fabric layers to the spot-welded Air Sprung Cell chambers. These loops allow the layers to be positioned further apart, creating larger air cushions when inflated - perfect for side sleepers. This design of the Ether Light XT Extreme Insulaiton Mat also requires less fabric overall, which means great stability and comfort with less weight.

Double layers of Thermolite insulation fill the Air Sprung Cells and prevent convective heat transfer from the warm body to the ground, while keeping the mat lightweight and packable.
