Sea To Summit Ether Light XT

The Ether Light XT Air Sleeping Mat is perfect for warm-weather backpackers looking for a quiet, lightweight sleeping pad that offers a high degree of comfort. The XT Air-Sprung Cells use loops of a 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.

ETHER LIGHT XT AIR SPRUNG CELLS

• Air Sprung Cells are the core technology used in Sea to Summit Air Mats and are the reason you will sleep more comfortably on a Sea to Summit mat than on a conventional air pad. Inspired by the springs of a modern pocket sprung mattress, dozens of interconnected chambers (called Air Sprung Cells) perfectly support your weight and conform to your body contours. The Ether Light range uses loops of TPU material to connect the top and bottom welds. This produces a thicker cell to give you a plush sleeping experience without compromising on Sea to Summit's Air Sprung Cell comfort.

INTEGRATED AIRSTREAM

• The Airstream Pumpsack is Sea to Summit's big volume mattress pump which we've now integrated into the stuff sack of every Air Sprung Cell mat. The clever design opens at one end to stow the air mat and the other end unfolds to become the built-in pump. The Airstream Pumpsack can be inflated with a single breath and takes just two or three cycles to fill mats. Not only is it faster than inflation by mouth, but there is minimal breath condensation entering the mat and it eliminates dizziness from blowing the mat up directly by mouth. The Airstream Pumpsack is also compatible with Sea to Summit's smaller multifunction valve, which is now featured on the updated Aeros pillow range, along with the Air Seats.

ASTM F3340-18 R-VALUE TESTING

• To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value. A laboratory-tested R-Value is the only way to measure resistance to heat loss. Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats. Since January 2020 we have used the industry standard ASTM F3340-18 test to provide R-Values for mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.

PILLOW LOCK SYSTEM

• The Pillow Lock System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019). Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics. All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock compatible by adding an Aeros Pillow Case.
