Tried it and didn't like it.I'm a bit of a wallet purist.. flat and mostly empty
It depends on your definition of what a "wallet" is. I always have a flashlight in my Bill's urban wallet-like contraption... along with a Spirit, Fisher space pen, lighter, paracord, Vic corkscrew, mini screwdrivers, sliver grippers, Fresnel lens, ikea tape, centipede, 16gb mini flash drive, 4/7 whistle... plus the usual couple of credit cards, cash, driving license and id card, etc...
Which one? Let's see it.
