I have bought dozens of "compact" money/ID wallets before this one, and they were always too thick to put into your pocket, and the ID holder was always a slide into pocket with nothing to keep it from falling out! This one is great! I have had no problem with the zippers. Or with my cards fitting, all good here. I love the fact I don't have to carry a large wallet or purse in the summer. Fits right into pockets in my cargo shorts, shirt pocket, or in my hiking pack! It comfortably holds my ID and 4 other cards with room for some cash without looking over stuffed. The outer pocket with key ring is a slide into pocket with no zipper or anything to keep it closed. The little chums penguin plastic logo on the other hand is...well.....kinda silly, but I suppose if it really bothers you, you could try to slice it off! Other than that I love it & will get more to give as gifts to friends who are outdoor activity people or who just don't like carrying every card they own all the time!  Dimensions: 4 1/4" W x 3" H and about 1/4 thick depending on how much you jam into it! Tough nylon, good seems.
