Integrated Airstream Pumpsack – The Airstream™ Pumpsack is Sea to Summit's big volume mattress pump. 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 the mat. 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.

Single Layer Air Sprung Cells – Inspired by the hundreds of springs found in a modern pocket sprung mattress,the hundreds of small interconnected chambers 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.

Multi-function Valve for Fast and Easy Inflation, Deflation and Fine Tuning of Air Pressure.

Includes – Quality stuff sack which doubles as a pump, a repair kit containing six self-adhesive patches for repairing punctures in the field, and two spare silicone one-way valve inserts.

Anti-Microbial Treatment Added to TPU Lamination – To prevent delamination/mold issues caused by moist air trapped inside the mat.
