SEA TO SUMMIT DRYSAC 20 L AIRSTREAM

Large volume inflation system for Sea To Summit mattresses. The Drysac Air Stream has an inflation nozzle at the bottom of the bag and allows you to inflate a mattress using the air trapped in the bag. To refill the bag with air, simply open the bag and blow lightly into it to give it its inflation. This prevents excess condensation inside the mattress. The Drysac Air Stream can be used as a normal Drysac or a liner pack.
