I have a front pocket wallet from Cabela's. I hate giant ass wallets under my ass all the time. Plus I don't keep anything in it but a bit o cash and a couple cards.
Cabela's has several different wallets. They're private label, so they aren't designer prices. Check this
Link.
If you haven't tried a front pocket wallet, I would recommend it.
EDIT: They have some buffalo skin wallets that are tougher, if you think you must.
