I ride with one of these in socal, so not too much worry about wear from the rain. I love it - looks less sporty than other panniers, and i got an inexpensive canvas strap to hook to it for classes, shopping, and generally taking it off the bike. It's HUGE too, and has a good liner that you can take out if you really need to stuff the bag. Not as high tech as other cycling brands, but for the price, look, and function, its wonderful.
