I don't own anything with a Harley logo, but I do own that same rainsuit. It is terrible. The pants are lined in something that wicks the water up inside, and the jacket cuffs are too tight to get my glove gauntlets inside very easily, so getting into the jacket takes forever. I replaced it with a cheaper rainsuit that doesn't have any lining in the pants, which makes them much more effective.
I'm going to look for some of these Gore-tex suggestions. Cabelas isn't far away.
(The Klim stuff looks great, except for the big flashing sign on their site that says "No girls allowed. Amazon women keep out!")
