Did the bag now for almost 2 years. 1 year of which she was about 3 times a week in use. Had my 3 kg heavy notebook in her. Together that was pretty hard. It brings (if you can bear it), two complete large folder pure. Rear fit again some purely of paperwork. I always had a great Leitz folder and a 1 liter bottle of water here - went without problems. The build quality is amazing. The bag still looks like new. The shoulder strap has the quality of a car safety belt. Can it therefore only recommend. Price / Performance Top.
