Rucksack for secondary school

[Dinosaurfossil]

I need to purchase a black secondary school rucksack to hold a laptop and the usual school stuff.
I'd appreciate any recommendations on brands/types others have purchased, thanks.

Jansport or Sporthouse, both excellent, not sure if they come in black

Jansport was the only one which survived a whole year during DD's Y7-11 and is still good enough for another year. And DD is a form of human squirrel regarding the content of her bag.
