I just received my strap and it answered my questions right away. How much money can I put in the belt? Answer: $2200. The zipper is very long and if you assemble and fold a pack of 4 bills, a thousand dollars will fit inside (assuming those folded bills are a hundred thousand). The buckle feels solid and so far the strap looks well made. I'll see how it holds up on 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.
