I got them from that place that is across the street (eastwards) from MEC in the big ugly white building. Coast Mountain sports? I dunno... They were the same price range.

I wouldn't call them waterproof... They aren't bad, but you will get wet if its raining enough, and especially if you wear shorts over them like me. Between the combination of not having mudflaps (my shins get soaked) and wearing shorts over (the wet cotton seems to force the water through the cycling pants), I'm still pretty soggy by the time I get to work. I haven't compared any other cycling pants, but you might as well try another brand as mine aren't anything to write home about. They are really nice and warm though, although that can be a problem in itself!
