It is hard to find a wallet that can includes all your cash cards and documents when traveling but Dango Projects may have you answer. The P02 Pioneer travel wallet is made from a coated fabric called DTEX, plastic zippers, and metal buckles. Features are zipper pockets, half fold layout with cards and cash compartments, and it comes with a detachable shoulder straps. In case you do not want to hold a pen, it has a small pen compartment. Made to be durable and resistant to the weather at a cost of $100. It is now available.
I like the look of this wallet, it does not look like a sling, a fanny pack or even a messenger back. It is a hanging wallet. I do wonder how many men in the world uses these types of wallet.
