The Air Sprung Cell™ technology provides great body support while sleeping – each cell behaves independently and does not affect one another (you don’t feel like you’re "floating" when tossing and turning).
The sleeping pad is constructed from 30D/40D high-strength nylon that is quiet. To prevent mold growth inside the pad from the moisture in exhaled air, it is treated with an antibacterial coating on the inner side. The package also includes a pump sack for easy inflation.
In the chambers of the sleeping pad, we find a double layer of THERMOLITE® synthetic insulation, which prevents the loss of body heat to the freezing ground.
Ether Light XT™ Insulated stands out primarily for its thickness of 10 cm, so it reliably compensates for any unevenness of the surface.

Handling it is a breeze. Quick inflation and deflation, and the ability to adjust the firmness of the sleeping pad.

By opening the first section, you can inflate the sleeping pad and the air does not escape. Pressing on the orange dot in the middle will release the air.

Opening the second section will release air from the sleeping pad in a few seconds.

The sleeping pad has a thermal resistance value R = 6,2, which is reliably sufficient even for winter conditions. Sea To Summit sleeping pads are tested according to the ASTM F3340-18 standard. If another manufacturer uses this standard, you can easily compare sleeping pads across brands.
The sleeping pad features the unique PillowLock™ system, which allows you to easily and securely attach any Sea To Summit pillow to the sleeping pad so that it doesn't slip away.
With the sleeping pad, you will receive a small storage bag (stuff sack) and a pump sack in one (62 g) and a repair kit.
