Frequently Asked questions
Can I use the dry sack pump for paddling?
No. The featherweight fabric on the dry sack pump is not designed for the sharp and abrasive objects and surfaces found in boating and marine environments. However, it's a perfect dry sack for storing clothing and towels inside your backpack.
Will the nozzle fit the Aeros Pillow valve?
No, the nozzle on the dry sack pump is only designed to fit Sea to Summit's Air Sprung Cell and self-inflating sleeping pads.
Will the dry sack pump also work as a protective bag from bear and critters?
For protection against wildlife, we recommend a dry sack like our Lightweight Dry Sack. This dry sack pump has fabric that can snag on branches or even rough tree bark, giving critters a way in.
