I use my trusty 07 black rh day bag. It's taken a beating through rain and sun, and although it looks a bit worse for the wear, I'd rather get that wet than any of the other bbags. I figure I can have one for bad weather. I don't use any other bags, so it's my only option. But I've been known to put the day bag under my coat or jacket in the rain. I look a bit weird and bulg-ey, but it's worth it. Have to say that sometimes I do feel a bit ridiculous protecting the bag like it's a baby...
