The (blue-gray) bag is for one year at each smaller bike on the rack and still looks like "fresh out of the store." The material is very durable and all functions (zippers, snaps, Porters - suspension, etc.) are completely intact. As Pannier extraordinarily elegant - also handy for "small purchases in between".
The build quality is top notch - ie: a total of at least 5 Stars.! The purchase can I fully recommend.
