The Airstream is Sea To Summits volume sleeping mattress pump, it is based on their 20L Ultra-Sil Nano dry sack, with added valve plug and foot loop. Using the venturi effect means the 20 litre Airstream can be inflated with a single breath.

Two to three cycles from the Airstream are enough to fill Sea To Summit sleeping mats, meaning you’re ready to go quickly, with minimal breath condensation in your mat, or dizziness from blowing the mat up.

The Airstream can be used as a 20 L dry sack, or as a vaccum bag to store your down sleeping bag.
