Sea to Summit Air Stream Pump Sack

Pack sack during the day, pump for the night. The Air Stream Pump Dry Sack has a flat valve that can be connected to the multi-function valve on all Sea To Summit sleeping mats. With two to three air cycles, your mat will inflate with minimal condensation on the inside of the pad, so you won't get dizzy from blowing. The lightweight 15D-Ultra-Sil Dry Sack is large enough to stow clothes or a sleeping bag in your backpack.
