Am absolutely satisfied with the backpack, bought one for myself and my colleagues. We wanted for our cycling a smaller backpack and here for the batch with 10L right. It fits more into it, as I had at first suspected, get the pump, spare tube, tools, ... easily clean and still have room for a snack and some clothes to change into. The hydration bladder is somewhat more complicated reinzustecken, but ideally placed. It sloshes not and is ideal to wear. In short, I would buy it again.
