After a brief e-mail and the proposal on my part that only the top pocket would be exchanged, I have over 15 minutes (!) Get a very friendly answer was in the asked for my address. The next day (!), I had a package with the new top bag in his hand. The old bag I have returned with the help of paid return label.
It may be that they are not here to a premium product such as North Face, etc., this can be seen already in the price. However, the manufacturer stands by its products and exchanges defective goods very quickly and without discussion. This behavior vs.. their own customers is my 5 star!
