I'm looking for the best rain coat ever. I want something that is a shell only, no insulation so i can wear it most of the year by varying insulation underneath. I would like something completely waterproof, not resistant, and i also don't believe all that much in "breathability" of fabric. That being said i would like a jacket with venting options to help regulate internal humidity. Something that is form fitting and bike specific would obviously be best. Price is secondary to performance. Any help is aprreciated.
