Another vote for ZCP - I prefer zip around wallets and don't like chunky ones.
Every once in a while I get so many coins I worry about straining the zipper, and switch to a (non-LV) wallet with more space for coins - but I always go back to my ZCP once I spend some of the coins.
I want to get a cles for excess coins, but the ZCP is fine for the number of cards I carry (I double them up). I'd rather carry two pieces than a bigger wallet, I looked at the Zippy Wallet but it seemed too big to me.
