when I commute on my roadie I wear my back pack. it makes me sweat, but under 65F not much mor than without. a couple of years ago I got the idea to put a mesh back rest (like the kind mused on office chairs and car seats) between the backpack and my back. it pushed my shirt against my back and I sweated any way.
