This is a wonderful idea but have one better. Strap a small air conditioner to your top tube and when it warms, fire that mother up. Be sure to carry lots of extension chord.
Seriously, instead of a jacket, wear a vest/gillet and Lycra arm warmers. When it gets warm, off come the arm warmers and into your jersey pocket. And when warmer still, the vest can be rolled up into another jersey pocket.
