Our son ((3rd class)) is built rather narrow and had the most knapsack problem that he could not get anywhere because the satchel survived on the sides. We had a well of Wolfskin and even this was too wide but otherwise very well made and is by 2 school years still in great condition and although the kids before (unfortunately) shoot these things across the schoolyard. In our search for another Alternatiove we found this backpack-satchel and Usner child uses him now since the summer of 2014. He is prima cope with it. Selfless leaves unscathed at home. plenty of storage space and easy to clean. The gym bag can be fixed on the satchel really good and thus on the way to school the children have their hands free is a really great idea. After explaining time it was our son easy to install these automatically with a few simple steps and take off. The sports bag is filled eingeriollt and then also remains really :) thanks to the Velcro and then clicked only the satchel. Even if is for the swimming lessons the satchel indians school it can be taken without any problems. Handdtuch and bathing suits fit into or even sports shoes and clothes. With the pencil case, I regret to give right. But I must say I've seen of yet no reputable brand adequate school pencil case. The pencil cases and pencil cases all have their drawbacks. We have the combination Case of Wolfskin dazugeholt then and that it may be at least approximately ((Penbox from Jack Wolfskin, a pencil case and pencil case Hybrid Expandable but better than two pencil cases that are indeed dragged and could go conceded or forgotten.))) So all in Overall we are very happy with the choice of this satchel and our son also. And the extra compartment with zipper in the lid also provides again an opportunity for quick access. And despite the rain, the contents of the knapsack was dry and clean at school or at home. We would want to buy it again at any time and also recommend.
