These are great bottles. The shape and design are the same as any good bottle but I just think that the Caffeine & Cols logo is cool and very much in sync with my personal style and riding environment. I live in the Var region of France and ride the Cols every time that I go out. I just have to remember to screw the top on tightly and not pour water all down my jersey next time.
A bidon is a bidon, too a certain extent. But these look very smart.
