I agree I didnt think the willie & max bags would hold up to well either. But I had mine over a year and use them regularly. Mine are too small but that's my fault. Anyway they have held up pretty well and mine are mounted with the easy bracket set up.Which was to easy with the sissy bar but the easy bracket folks sorted it out pretty well. Anyway my point now that im finaly too it was after riding in a steady down pour for and hour and a half I was really supprise to find the contents nice and dry. So I will give them that.
