With an R-value over 6, the 10cm thick Ether Light XT Extreme air mat redefines lightweight sleeping comfort for winter adventures around the globe.
Sea to Summit’s Air Sprung Cells are the reason you will sleep better on this air mat. 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 the extra thick (XT) EtherLight design, many TPU loops are used to connect the top and bottom fabric layers to the 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.
Dual-density layers of THERMOLITE insulation fill the Air Sprung Cells and work together to prevent convective heat transfer and boost warmth while remaining lightweight and packable.
When the mercury drops, the EtherLight XT Extreme’s 6.2 (women’s 6.3) ASTM R-value will keep you cushioned and insulated from the cold hard lumps and bumps beneath.
Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell™ dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall.
Refining lightweight cold-climate sleeping comfort, the EtherLight mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum® and THERMOLITE® insulation with a loop baffle Air Sprung Cell™ construction to create a 10cm thick mat with an incredibly low weight and small packed size.
Air Sprung Cells operate in the same way as a pocket spring mattress, as each cell deforms independently the mattress conforms to your body shape which feels softer and more comfortable with more body contact area and even dispersion of pressure.
Exkin Platinum® is a very lightweight, quiet non-woven fabric that has a thin metalised layer applied to the surface. Exkin Platinum® thermal technology reflects radiant heat loss back to the user.
The THERMOLITE® insulation lofts up inside the Air Sprung Cells to prevent convective heat loss from your warm body to the cold ground.
Multi-function valve integrates an 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 for comfort, in one compact, low profile unit.
All Sea to Summit sleeping mats include the AirStream Pump-sack free with your premium mat, plus a small repair kit containing six self-adhesive patches for repairing punctures in the field and a spare silicone one-way valve flap.

ASTM F3340-18 R-values
An
R-value (Resistance-value) is a metric used to rate how effectively
your sleeping mat resists heat loss. It’s the only way to know how well
your mat will prevent your body heat being leeched away by ground
temperatures (which can be a lot colder than air temperatures).
Sea
to Summit our mats are independently tested at a laboratory to
precisely controlled standards. The new industry standard ASTM F3340-18
testing has now been introduced and all Sea to Summit mats released from
2020 onwards are tested to this standard.
