In the backpack does not fit so insane amount of pure (with a notebook + charger, a small folder, pencil case, block and sweater he's all right full) and I have a feeling that the zipper is very noisy.
Update: On May 25, 2013 I bought the backpack. On 28 April 2014, and therefore not even a year later, I have discovered first damage caused by wear. However, one must also say that I use the backpack daily.
