I just finished a trip where I used a wallet called Big Skinny that I won for free in some online contest. In general I liked it but the zipper was kind of pointless and got in the way of getting cash and the slots for cards was a bit loose. I started to think about asking TB to make something similar but I'm not sure if that is necessary.
I own the TB wallet (2 of them in fact) and I just can't use it as a real wallet because of the hook. I could take that off but I generally don't like to break things like that. I also think it's bigger than it needs to be since cash folded in half has tons of extra room in the wallet. I guess I am asking for something new after all.
I'd like to see a TB wallet or another version for those who want to carry it in a pocket. You could probably get away with an O ring but the hook seems to be a definite no-no if you ask me. I think the size should be smaller than the current one. I'm not sure a zipper is really need either. The zipper keeps change in the current wallet but in this case I wouldn't want this for change.
Any other thoughts?
