This backpack has one large container capacity, is stable and definitely waterproof. However, I can not carry him on his back and therefore it is in my opinion a bad design. Without any padding or hip belt, it is extremely painful to wear this backpack on your back. No matter what you do in the backpack, with the volume of the backpack has now filled by a considerable weight and that does hurt unlikely, no matter how I grab the content. Who is interested only in a dry bag, the likes like this backpack, but anyone who is planning to carry this thing for more than 2 minutes on the back, which I would advise against this article. I have the Ortlieb proposed customer service to provide future versions of this backpack with waist belt and / or a padding - I was told that this article was not intended to longer carry him on their backs. If I had known this just before buying.
