The Porcelain Rocket bags are for a Jones which my father rides. He has some truss bags, a top tube pack, and a loop bar pack. They have been used and abused and take whatever is thrown at them and continue to function perfectly and are incredibly durable. Just comparing side by side to my Revelate gear (which I think is fantastic), the PR stuff seems to have a bit more thought put into some of the smaller details like webbing sewn onto the bags to adjust strap placement and light stiffener plates put into areas that may be prone to folding or being squished. Overall it is just awesome gear.
