Sea To Summit Ether LightXT Extreme Insulated Sleeping Mat – Rectangular – Large

Our lightest and thickest full size Air Sprung Cell Mat with insulation for all-season comfort. When we set out to design a mat that was better than what was already available, we ultimately went back to why we carry a sleeping mat into the wild in the first place , to give us a better night’s sleep. Better’ is of course a very subjective ambition and while we could have made the lightest, or the most compact mat ever designed, we’re stoked to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping!
