Use the Sea To Summit Air Stream Pump Sack to quickly and efficiently inflate your sleeping mat. This 20L pump sack can be inflated with a single breath (thanks to the physics of the Venturi Effect)! Two to three full cycles are enough to fill Sea To Summit Sleeping mats so no lightheadedness from blowing it up or excess breath condensation inside your mat. As an extra bonus, the Air Stream can be used as a 20L dry sack or as a vacuum bag for your sleeping bag when you're not using it for inflation purposes. Who doesn't like a three-for-one?!
