The eco-friendly, PVC-free Mineo Transformer Backpack 20 can be clipped to your gear rack as a bike bag; it doubles as a comfortable business backpack and has trolley sleeve for travel as well. Attach and detach your bag to the gear rack quickly and easily with the adjustable Plug and Ride system. The guide rail just disappears in the quick stow compartment when you put your bike pack on. A spacious main compartment as a slide-in pocket for laptops up to 15.6"" as well as a place for writing utensils and your water bottle. Another front compartment and a safety pocket at the back will keep your phone and documents close at hand. A super-practical key-holder cord on the padded shoulder strap makes unlocking doors a breeze and the stain-resistant material is impervious to challenges of today's urban jungles.
