LOL. You Texans just need to harden up!

Seriously, most of my experimentation with rain gear for touring has been through commuting, and if you're going to commute year-round here you're going to ride in the cold and wet sometimes. And LeeG is dead right. Gore-tex is great in cold conditions, because it keeps the rain out and you don't sweat as much. But like anything else, it doesn't breathe fast enough if you're warm.

Capes/ponchos are great for rain, but act like a sail if there's any wind.
