Haven\'t had this out in the weather yet, but so far so good. I find it to be just the right size for what I need, although I\'ve yet to try riding with it expanded. Nice feature if you need it, but if you need it expanded often you would probably be better off with something else. At first this bag looks pretty small, ( the curve of the \"tank\" steals a lot of volume ) but as you start filling it up it holds quite a bit. Mounting points fit well, although the front hooks leave quite a bit extra strapping to tuck in somewhere out of the wind.
