I've always hated bulging wallets, specially if you put them in backpocket. No wonder so many people want to improve them. I've been using slimfold wallets (http://www.slimfoldwallet.com, no association) for a while. It's made out of Tyvek and is so thin - even with 10 credit cards in it it's thinner than my previous leather wallets emptied. I don't like the soft shell wallet they're making now, thicker than the Tyvek ones. Worth a look.
