For quiite a while I'd had the idea of making a dry bag - not the normal ortleib type thing, but one with a drysuit zip and an inflator. When I heard that Balders from Reefers and Wreckers was able to put something together for me this was made. I gave him a design and and old drysuit zip and he did the rest.

I opted for a Buddy (A.P.) valves BCD inflator so that it could swivel, allowing the bag to be packed in a tackle bag, with the inflator sticking out of the top.
