Details & Specs
For expeditioners seeking the lightest, most insulated, and comfortable mat for cold climates, the Ether Light XT Extreme Mat from Sea to Summit will deliver.
This mat takes the design of their original bestseller and makes it warmer so you can snooze comfortably when the temperature drops. The Air Sprung Cell construction conforms to your body for support, providing 10cm of stable comfort with a quiet and grippy 30/40D nylon face fabric. There are dual-density layers of THERMOLITE® insulation which provides an ASTM R-value of 6.2 and there’s an anti-microbial treatment added to prevent mould growth inside the mat. It’s fast and easy to inflate and deflate thanks to the multi-function valve, and it comes with an airstream pump sack integrated into the stuff sack to assist inflation.
If you need to make any repairs in the field, there are self-adhesive patches included as well as a PillowLock™ system to stop your existing compatible Sea to Summit pillow from sliding around at night. Snooze soundly on your lightweight and speedy cold-weather adventures, with the Ether Light XT Extreme Mat from Sea to Summit.
