I don't use bike specific clothing because I hate how it looks...it's just not my style, however I do use "technical athletic clothing" and outdoor type clothing.The number one reason why people sweat too much is because they overdress, ride too hard and are out of shape. My commute is 12-14 km one way and I can ride in such a way that I hardly break a sweat, it all depends on how hard I ride and how many layers I wear.
