I had this bag for a little over a year - was great until I used it in the winter - the plastic clips that keep the top closed become drittle in the cold. One snapped, and I can no longer keep the top latched.I called Canon parts and they don't sell parts for the bag - so this bag will end up in the trash.I have a Lowepro backpack also and love it. I'll have to buy one of their smaller bags to replace this one.
