I just received my belt and it answered my questions right away. Answer: $2200. The zipper zone is very long, and if you compose and stack a stack of 4 bills, a thousand dollars will fit (assuming those folded bills are a hundred). Well done. I'll see how it holds up during my trip to Vietnam. I edited this review because I'm leaving for Vietnam tomorrow and my belt is full of $22 bills. I still have room if I need to store more. I think the maximum I could keep on my belt is $3,500 in 100 denominations.
