Great product, however, I couldn't fit them to my bike as intended, so had to strap them to a luggage rack, on top of each other!
They were stuffed to the gunnels every day, over 9 day's on a two up trip to the orkneys and back from Devon, 0ver 1500 miles In torrential rain, and they did not leak!
A buckle on one of the shoulder straps did break, but I was using them to strap luggage down, which is obviously not it's intended use.
So all told, a quality product, and extremely well made!
