I named this style after the Buenos Aires neighborhood that my mom lived in as a kid. It's a great area in a great town- I highly recommend.
The bag is a Messenger style with a strap that allows for either shoulder or crossbody use. The skin is a very special nubuck that has fine cuts throughout, creating a scale-like appearance. The flap is made out of a supple saddle leather, and the strap is made in a mid-weight waxed skin. I found the amazing gold lion's head hardware many years ago in Egypt. The lining has a patch pocket for easy access to phone, keys and other things that you need to get your hand on quickly.
