The exterior of the case faded quickly. That doesn't look nice anymore! I wore it before our first hike in June! At first I was happy. But I can take it off and replace the faded fabric! Oh, and one more thing, the derailleur that holds the rope in place wasn't working, or it was too big for the rope/cable holding it in place during that first ride. the spare tire fell off and someone told us we stopped and took it off. I had to thread a larger diameter rope to accommodate the cup.
