It seems to be a sturdy construction with robust zippers. Maybe I didn't calculate well, but it is quite long while not so tall. Time will tell, and I hope it is like the school bags from this company that turned out to be immortal. The three we have lasted 6 years and are still functional.

One of the best travel bags. Very good and durable material, two wheels so you don't have to lift it and a folding handle. It is the second one I buy, as the first one is in excellent condition after long use. Recommended by me.
