Henry, there more to it than that. Out west, the climate is naturally warmer. Assuming that's where he is, up in the alps like that still doesn't compare to a place like Edmonton where it's generally freezing.
As for the jacket itself, depending on your location you may not need such a thicker or warmer coat. Though this is a local forum to me, and many other Ontario riders post on here, there are still people who don't need all that many layers.
Maybe next time take into consideration where he's posting from, and try and help him.
