UOG TOP PICK - Sea to Summit Ether Light XT Sleeping Mats - Best combination of comfort, weight and pack size - We've singled out Sea to Summits Ether Light XT Sleeping Mats as one of our top recommendations because they offers exceptional comfort in a very light and small package. Ideal for side sleepers thanks to it's impressive 10cm depth.

Sea to Summit says:

Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.

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.

The Sea to Summit's Ether Light XT Air 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 for some other inflatable mats.

The depth of the mat sets it apart from its competitors and 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.

A total surprise!

This was a total surprise, but this might be the best piece of gear I've bought in a while! Before, I owned a ThermaRest Prolite, and the difference this thing makes in comfort is night and day. This thing is seriously more comfortable than airbeds I have bought for indoor use, takes up less in my pack, and inflates super quickly. I'm actually irritated with myself for not investing in this comfy a night sleep outdoors, I just didn't think it was possible. Have only used the NeoAir a few times, but I think this is definitely comfier (although I understand also marginally heavier, CON).

Side note: I got a free Aeros Pillow with this purchase. I thought the combo of S2S pillow and mat was a bit of a marketing gimmick, but I have to say I am impressed by how well it stays in place using the compatible grippy materials on both products. Normally the pillow just slips off of camping mats halfway through the night but this thing stayed put for me. Would definitely recommend the matching S2S pillow if your are buying both. My only gripe with it is that the valve for the pillow is different, requiring you to inverse the original staff sack for the mat to inflate. WEIRD design choice but ultimately so trivial it almost doesn't bear noting.
