Women's UltraLight Insulated Air Sleeping Mat

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 hundreds of springs found in a modern pocket sprung mattress, the hundreds of small interconnected chambers (called Air Sprung Cells) perfectly support your weight and conform to your body contours. The Ultra Light range has a single layer of medium resolution cells to give you the lightest and smallest packed volume mat without compromising on Sea to Summit's Air Sprung Cell comfort.

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 our 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.

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 our 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.

The uprated high tensile yarn, high thread count 30/40D ripstop nylon face fabric of our Air Sprung Cell sleeping mats is quiet, light and extremely durable. On the inside, we apply a bright white TPU to make the fabric airtight and weldable - it also contains a permanent antimicrobial treatment to ensure mold will not form on the inside of the mat. These characteristics combine to form the strongest, most durable air mat fabric available. On the outside, we apply a thin proprietary coating to reduce the slipperiness of the surface, increase water resistance, and aid puncture repair with the included self-adhesive patches.
