I chose this wallet for a specific purpose, an annual fishing trip where we sometimes get wet. I wanted a wallet that would not let all of my stuff to get wet but would not necessarily hold all of my cards, papers, flashlight, and everything else that is part of my daily carry. This is a strange beast, and so far I like it.This is a small wallet, not big enough to carry everything you might want to carry in your daily kit but big enough to carry cash, some cards, a key and a couple of other small items. It measures about 6โx3.5โ which is very low profile and is well suited for shoving in a tight space. When zipped and empty it lays flat. It has a paracord lanyard on a carabiner-style clip, it has a loop for clipping, and it has a strap on the back for typing.There is a tag with the wallet that describes the zipper. The zipper is very stiff, and the tag says to close it tightly to maintain the waterproof feature. The zipper is so tight, in fact, that I was really worried I was going to destroy the wallet just trying to get the wallet open the first time. It is still very tight and stiff, but after the first open it moves a little better (though still very stiff).This is the first fully submersible wallet I have used. It is completely waterproof when the zipper is closed. The outer shell is made of a material that reminds me of a cross between nylon and canvas, The inner material feels like poured plastic on one side, and like nylon on the other side. The water beads and rolls off when the wallet is splashed.This is a good waterproof wallet, small, and designed for low profile storage/stashing. It is made very well, and it is very definitely waterproof.
