I've had a couple of timbuks, swore by them until I saw 31trum's Scott not Scot bag, for me they were the original courier bag, haven't brought one in a couple of years, but they are pretty water tight, the only thing is the corners get worn away if you have them for any length of time, always liked the customisable panel design, but you can only build your own on their website and they only deliver to the states. internal divider that I've got in one of my smaller bags, is a bit shit as it sewn into the bag at the bottom, along the backside, so its not really central and when tou have stuff in it, makes the bag kinda awkward to carry.
