I originally purchased this product to use as a wearable wallet when in situations that would not allow me to have a purse (dance club, walking/running, etc.) but I found that because I have extraordinarily tiny wrists, even at its smallest setting the wristband wallet was too large. Then I realized that I could put it around my upper arm like an iPod holder for jogging and it fit wonderfully. Because of that, it became my on-body wallet for travel, as I could easily remove it to pay for purchases and then return it to its place on my bicep. I'm sure that it would be an easy wallet to pick, but when hidden under my tshirt sleeve, it wasn't readily apparent and there was always en easier, more tempting, target in the crowd.

I like the fact that the interior pocket is large enough (barely; have patience) to hold a passport, and that even loaded up with 20 $1 bills and $5 in dimes, it was easy to distribute the bulk in such a way that it still closed easily around my bicep with very little apparent bulk. I didn't initially trust the velcro pocket to hold anything small (dimes, for example) for fear that they would fall out, but after a two day test I found that this fear was unsubstantiated. The flap and the velcro are more than adequate to keep anything small, inside.

With its two reflective strips, it is very obviously not dressy enough for a dance club, but if you flip it inside-out then you can velcro it around your ankle (takes some doing but is doable) and so you can, in a pinch, wear it to a dance club without looking entirely the fool (generally folks in dance clubs don't look at ankles so they won't notice its presence).

Finally, on trips I often do sink laundry and when the wallet does get sweaty, it easily washes in the sink along with my other laundry and dries overnight and is ready to go the next day.
