The Ether Light XT insulated mat provides exceptional comfort and warmth in a very light package.

Sea to Summit says:

Our lightest and thickest full size Air Sprung Cell™ Mat with insulation for all-season comfort.

Refining lightweight cold-climate sleeping comfort, this mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum® and THERMOLITE® insualtion with a loop baffle Air Sprung Cell™ construction to create a 10cm thick mat with an incredibly low weight. 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. Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.

The Sea to Summit's Ether Light XT Insulated Sleeping Mat impresses straight out of the box. It was straightforward to inflate with the the well thought out integrated stuff and pump sack. I found it surprisingly easy to roll up and fit into the stuff sack something I cannot say of some other inflatable mats.

The depth of the mat sets it apart from its competitors providing extra comfort and keeping you further away from the cold ground whichever way you sleep. The outer fabric is tough and grippy so the mat will stay where you want it.

ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.

Super Comfy

So comfy and stable. I wriggle around a lot from my back to my side to my front. The Ether Light XT Insulated Mat didn't move or squeak and was always comfortable. The weight and pack size is impressive given the warmth and depth of the mat.
