I'm finding this thread kind of late, but how about a woman sized cycling style hat? I've been looking for one that I can wear under my helmet on rainy days (mainly for the brim). I have an old one of my husbands - but my team mates make fun of me. They say I must be the only person in the world that can make a cycling hat (and especially the teeny brim they usually have) look too big.......

My husbands team hats are really nice nylon type material instead of cotton so they don't hold a lot of water if its mucky.
