I have the Fox Creek "Large Trucker" model with the chain. I like this style because it is thinner. I get a pain in my hip if sit with a tri-fold or bi-folding wallet. The chain is something that I keep on, but it is not why I bought the wallet. The chain is not long and it does not bump or catch anything when I ride.
As far as quality, it is the best, well made, durable wallet I have ever had, especially for $24. I also have a belt from Fox Creek that I am wearing right now. Best belt I have ever had, as well.
Fox Creek sells a giant wallet called the "Credit Card Trucker". It would not fit in my back pocket. It is huge and I am not a small person. Sent it back.
