Sea to Summit Air Stream Dry Sack

The Air Stream is a big-volume sleeping mattress pump, it is based on a 20L Ultra-Sil Nano Dry Sack, with added valve plug and foot loop. Using the venturi effect means the 20 litre Air Stream can be inflated with a single breath.

Two to three cycles from the Air Stream are enough to fill Sea to Summit Sleeping mats, meaning you are ready to go quickly, with minimal breath condensation in your mat, or dizziness from blowing the mat up. The Air Stream can be used as a 20L dry sack, or ultralight pack liner.
