Once the bag is now about 1/2 year old, I have to supplement unfortunately that also with me the seam has risen on the ground, so I can not use because everything would fall out. Apart from my thermos of coffee and some fruit, I had only a few papers here that hardly weigh anything. That can not possibly be too heavy.
All in all, the pocket a lot of subjects in which you can accommodate a lot but you can only carry light things - 2 to 3 books were permanently probably already too heavy. The quality leaves so much to be desired. The supplier wrote to me, that I have no warranty claims because the manufacturer is no guarantee.
The money you can save you if you want to carry more than a few list!
For this reason I can not give 5 stars more.
