Description || Ether Light XT Extreme Insulated Air Sleeping Mat


The Ether Light XT Extreme is extra thick and exceptionally warm. The XT Air Sprung Cells provide four inches of stability and comfort, while dual-density layers of THERMOLITE® insulation prevent convective heat loss and internal air movement. This results in true four-season performance.

Frequently Asked questions

Is this sleeping pad comfortable at this thickness?

Yes. Thickness isn't the key factor for sleeping pad comfort – the number of points of suspension is. Our air sprung cell sleeping pads support your body weight with hundreds of individually air-filled springs.

Is this sleeping pad easy to inflate?

Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly and easily inflate the sleeping pad. This means no hard work and dizziness for you, and practically no condensation moisture inside the pad.

Does the sleeping pad make noise when I shift around in my sleep?

No. The reflective material (Exkin Platinum®) and the outer laminate material are both very quiet. Your tent buddy will thank you in the morning.

Is the Ether Light XT Extreme Insulated Sleeping Pad warm enough for winter conditions and four-season use?

Absolutely. The tested R-Value of 6.2 of this sleeping pad and lack of internal air movement (which reduces heat loss) makes it perfect for colder temps and four-season use.
