Stolen from Bicycle Hacks but really posting here for others information and for others to suggest other little winter riding tips.
One way to fight damp, wet clothing is with newspaper. Way back in a Bike Hacks Classic entry I talked about how I will stuff my shoes with newspaper after a wet ride to help speed up the drying process. You can also use a rubber band to wrap the shoe with newspaper.
Well the same thing works for gloves. After a recent wet ride I reached for the newspaper and the result is simple and fairly effective. Even more effective is if you have an air vent in your office that you can place your articles near to help make it so you do not have to put on damp clothing later on.
