Description || Ether Light XT Insulated Air Sleeping Mat


At four inches thick, the Ether Light XT Insulated Mat brings Air Sprung Cell comfort to the realm of thicker air sleeping pads. Using two types of insulation for three-season warmth, this sleeping pad is lightweight and quieter than a traditional air pad. The XT Air-Sprung Cells are constructed using loops of strong, flexible material to provide a plush sleeping experience. The uprated 30D/40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.

Frequently Asked questions

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 Insulated Sleeping Pad warm enough for shoulder seasons?

This air sleeping pad has a tested R-Value of 3.2, which is enough insulation for use from late spring to early fall. For insulated sleeping pads that are better in colder conditions, look for pads with higher R-Values and 4-season use.

Is it suitable for backpacking?

Yes! The tapered regular size has a small packed-size and weighs just over a pound, making this sleeping pad ideal for backpacking and bike touring.
