Very good backpack with a small error

My son uses it for sports, football, etc. - permanent use.
Material very good, seams ok, but do not hold large weights. Shoe compartment is awesome, can also handle well.
Small deficiency: the zips go at large compartment on under load when you both draws in the middle to the top! Both the bottom of any page is completely okay - not particularly disturbing, but you can lose what.
What is missing: professional or small holder / rubber ring for a bottle!
But: good backpack.
