I have the R25 and it is a good pack. Not waterproof but water resistant. If riding in the rain, I would get the additional dry bags. It does lock down on your body with the front latch mechanism so I have had no feeling of it flopping around on my back at speed or turns. It looks a little like you are going off into battle with the buckles and front latch but highly functional. It will hold a laptop and expands pretty well. Not many pockets, so little things end up at the bottom of the bag. Overall a good bag, pricy but if you need the space and its not available on your bike, it will work well and feel secure on you.
