At first glance, TOP, but then I had him for two weeks (each 3x) in use on the way to swim training. Already saw the thing a little different. The Arena FastPack 2.0 can not pack so that the back no annoying bulge created. I have tried different quantities and the bead was every time. There is a weak point between the wet compartment and below the upper part of the otherwise well-designed product. Had the FastPack a lap belt, could compensate for this. I think you can already see on the product image, the thing knautscht back. Accordingly, it is a backpack for the passenger seat. Not suitable for me as a cyclist, because of the low Tragekonfort. I sent him back.
