I was looking for something similar a while back.
Nice idea...

If you skip to the end he shows you nicely.

Looks pretty neat!

I've been facying some of these for a while. They seem to be the perfect response to air-filled dry bags or dry bags with big valves on the side.

I'd be interested in knowing if anybody has any and if they're as good as they seem.
