The Sea to Summit Ether Light Extreme Sleeping Mat acknowledges the gap at the upper end of our insulated sleeping mats. It provides an option for those requiring the highest insulation.
With an R-value of 6.3, our 10cm thick Ether Light XT Extreme air mat redefines lightweight sleeping comfort for winter adventures. Our Ether Light Extreme sleeping mat offers dual density Thermolite insulation layers to provide the best performance to weight ratio. Updated construction techniques ensure a complete fill. These technologies work together to prevent convective heat transfer and boost warmth while remaining lightweight and packable.
Sea to Summit’s Air Sprung Cells are the reason you will sleep better on our air mats. Each Air Sprung Cell deforms independently and allows the mat to conform to your body shape. This provides support and comfort by more evenly dispersing pressure across the mat’s surface.
For our extra thick (XT) Ether Light design, we use many TPU loops to connect the top and bottom fabric layers to our Air Sprung Cell dot weld pattern. These loops allow the top and bottom layers to be positioned further apart which creates larger pockets of air when inflated – perfect for side sleepers. This design also requires less fabric overall which means great stability and comfort for less weight.
