A needed accessorry - Big Agnes Pumphouse Ultra Multiuse Dry Sack and Pad Pump

Anyone who doesn’t have this is really wasting their time. This works very well as it’s intended purpose but I would be hesitant about using this as a dry bag or camp shower. The design is fantastic since it uses a second line that expands and creates double the size to capture air. I have found it most useful to blow a couple times down into the bag which helps it open up and capture air. I wouldn’t chance using this as a dry bag for any items that could potentially puncture it, much cheaper to replace a traditional one. I also wouldn’t try to use this as a camp shower for fear of introducing bacteria into your sleeping pad. As a final suggestion to Big Agnes, this accessory should be included with every inflatable pad as it is truly an essential.
