Before reading the article I was surprised to find them similar to old german Sout backpacks. They are really sturdy and durable: your kid needs just one of them for all primary school (grundschule). They are explensive (not so much considering 3-6 years of continuous abuse by kids), but when the kid gets tired of it, some people put them on sale. I have one that I know was resold at least 2 times and it still in perfect shape... Great for airport travel, btw.
