There are two other quite large pocket for documents. The closures are sturdy enough and the material which forms the bag is as strong and is strengthening the bottom of the bag with foam and a waterproof material. The small waterproof protection that is effective on the rainy day and it is functional.
However, the handle used to hold the bag by hand is not very strong because at the end of a month he started to tear a little bit, but it did not damage the sleeves that are very good resistant and comfortable even if the bag is loaded.
I find the reliable and robust for its price (25 euros) if one seeks something solid cheap.
I recommend!
