Ultralight Air Sleeping Mat

Sea to Summit developed the XPRESS Valve to make inflation, deflation and adjustment of its air mats quicker and simpler than conventional air mats. The valve integrates a one-way inflate port, a rapid dump deflate port and a fine-tune button into a single, low-profile unit. The XPRESS valve fits the nozzle of the Airstream pump integrated into the stuff sack supplied with your Sea to Summit Air Sprung Cell 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.

Sea to Summit uses an anti-microbial finish in two different applications. The internal laminate of Sea to Summit Air Sprung Cell mats is treated with an anti-microbial compound to prevent mold (which could otherwise result from condensed breath moisture remaining in the mat for long periods). The fabric of Expander liners has an anti-microbial finish to keep the knitted poly-cotton fabric fresh and odor free. Both finishes are permanent.

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.
