This wallet is pretty good. It's slim, though not as slim as my money clip wallet. But it's easier to get at the cash when you need it, instead of muddling around with a wad of bills.
The chain hangs out the back of your pants in order for grab at easily. If you're in a place where theft is a problem, you can also loop it around a belt loop to prevent pick-pockets from gaining your cash super easily. But I still think it's better to put your wallet in your front pockets if you want to be absolutely safe.
The quality is fairly good overall, it's just the chain that bothered me to the point where I couldn't use the wallet. It's a major part of it too, but it either pokes into your bottom or clangs around when you try to sit. For some people you might enjoy it, but for me it ended up being a deal breaker.
