Sea to Summit Air Stream Dry Pump Sack
Sorry, this item is temporarily out of stock.
The Sea to Summit Air Stream Dry Pump Sack is a big-volume sleeping mattress pump, based on their 20 Litre Ultra-Sil Nano Dry Sack, with an added valve plug and foot loop. Using the venturi effect, 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’re 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.
