This is a Montana Billings Urban Leather Black bag. It is washed leather (like Campomaggi), but much lighter. I sold both my Campomaggi bags. They are absolutely gorgeous and the quality is spectacular, but they were so heavy. This one has much the same leather but is not heavy. Plus the price point is much lower.
This bag has an external slip pocket, an external zip pocket, an interior zip pocket, and an interior slip pocket. I wear it cross-body to distribute the weight better. The hardware is heavy duty and not shiny, which I really like.
This one is really nice because I can fit a personal size ring organiser in the large compartment, and my phone in the smaller one.
This brand also does smaller bags in washed leather, which are big enough for a phone and a wallet. They have totes in non-washed leather, though I prefer the washed.
