Brand new Crumpler Doozie backpack.
Unused as it was not quite what I am after, but a very good bag. The bottom compartment includes a removable camera pouch, could also be used to store snacks or items you do not want crushed in the main compartment.
Internal compartment includes a inner sleeve for a tablet or small laptop.
See photos for details.
