Sea to Summit Airstream Pump Dry Sack helps to reduce your pack size, thanks to its clever combination of two products into one. Based on their 35L Ultra-Sil Nano dry sack, this big-volume sleeping mattress pump has an added valve plug and foot loop for easy pumping. Inflated with a little more than a single breath, you should be able to fill your Sea to Summit sleeping mats in as little as two to three cycles of pumping. When finished as a pump, the sack can then be used as a 35L dry sack or ultralight pack liner.
