I use a Shower Pass Elite 2.1 and a helmet cover but use the cover only in the daytime as I have a helmet mounted light. Some day I will buy the optional hood for the times I am off my bike.

The absolute best rain jacket I use is the Patagonia M10. This jacket puts my Shower Pass to shame. This one is not cycling specific but keeps me from getting soaked. This one has a hood but I don't use it cycling. It also was double the cost of the SP.
