I have a Nike sling bag that has a caribeanor lock on it( that's right its attachable with a lock.). I bought it back in 2004 and it has a expandable mess fabric construction, a bling pocket, and a cool pocket on the back. It literally has the greatest feeling strap. I added a belt to it to keep its rotation around my torso from slipping. I think they stopped making them but I would buy another if I could find it. If anyone knows please PM me.
