I just started commuting to and from work. Its a little over a mile one way and pretty easy ride. My question is , what do you guys do about the heat issue? Its been getting pretty warm here lately(upper 70's mid 80's) I don't work until usually 6pm so I give myself about half an hour to get there so I have some cool down time. But usually by the time I get there I am swetting like a pig.

I wear my work clothes on the commute, black slacks and a button down white collard long sleeve shirt. Not the most friendly clothing for the weather I described.

Any thoughts?
