I have been using triple wallets for many, many years as I find them smaller and easier to carry in my back pocket. The triple fold I'm replacing was good, but the fabric material was quite thick. So I found this big skinny wallet, which is about the same size as most (if not all) triple folds. But its material is very thin. So that's the secret of its thin profile. It feels very durable and fits comfortably in a back pocket. One minus point: business card slots are perpendicular to the top opening. 3 slots per flap: 2 slots slightly less than the depth of a credit card and 1 slot the full depth of the flap. The 2 shallower slots are handy for storing credit cards and keeping them easily visible. But the deep third slot won't let you see a credit card at all - and it will "get lost" in this pocket. Luckily, I really only have 3 cards that I want to hold in my hand, so 4 slots that allow me to keep my cards visible is just right for my needs. But I prefer a wallet that has the card slots oriented so that the cards can slide in the same direction as the top bill slot. This allows 3 card slots to be placed on each flap, each of which is immediately visible to all cards and they can "peep" through the slot opening. Big Skinny should offer this option. I would buy that.
