Lowepro Omni Trekker.

These are rare to find these days. Especially in mint condition like this one.

They're a clever design that can be converted in seconds from a shoulder bag to a backpack. They're also designed to perfectly fit inside a Peli 1550 hard case so that you can use the case and bag as a divider system.

I had been after one of these for ages, and the concept is perfect. But unfortunately it wont take modern gripped bodies upright very well. So I've decided it's not for me.

Still has the tripod straps, shoulder strap and all important back pack harness.
