Sea to Summit Drysac Air Stream

High efficiency inflation system for Sea To Summit mattresses. The Drysac Air Stream is equipped with an inflation nozzle at the bottom of the bag and allows you to inflate a mattress thanks to the air imprisoned in it. To recharge the bag, just open it and blow slightly inside to restore swelling. This prevents the formation of excessive condensation inside the mattress. The Drysac Air Stream can be used as a normal drysac or a transport bag.
