The Sea to Summit Ether Light XT Insulated is their lightest, warmest and most cozy sleeping mat yet. The Ether Light XT Mat has Extra thick loop baffle air sprung cells™, that create larger air pockets while using less fabric. This allows the Ether Light XT to be lighter and smaller, without compromising on comfort. 30/40D Nylon fabric is light, quiet, and most importantly easily repairable with the included self-adhesive patches. All this combined allows a comfy night's sleep in all conditions.
