Good catch GoatMan with the waterproof wallet, I had got that when i had gotten the sparky to give me more room for the PSK and hadn't even got to test it for water yet. I have a vacuum sealer at the house and have been putting the contents of a lot of items in freezer bags cut to go in the space and pulling a vacuum on them to gain as much room in those pouches and add as a extra waterproof protection. Most everything in the kit can be submerged without concern for the bag but I will look at the bags design and have to make sure if I continue with it that water resistance will have to be ruled out. What did you end up going with, I'm trying for max space with min volume and using vacuum bags are helping a lot in squeezing more items in the little space that I have.
