I not a real believer in its effectiveness, but I admit that I own a set and use it regularly. To me, it's one of those things you buy if you have $150 burning a hole in your pocket and already have the other essentials for your setup. I use it along with the soap/shampoo/scent killer spray. I think the detergents/soaps/sprays are more important than the carbon. I use the carbon clothes because I paid good money for them and if nothing else, they provide another layer to keep me warm. That said, I think it has little impact on your "windability". I speak from experience.
