Nice and sturdy backpack with a zippered compartment at the front for small items. On the inside of the bag you will find a pocket across the entire back that closes with velcro. The main compartment is spacious and has a reinforced base, which helps the bag keep its shape. Takes A4 files.
 
You can store a surprising amount of stuff in this backpack. The bag is comfortable to wear due to the adjustable shoulder straps and sturdy handles.
