I get funny looks but I come from a Hockey background so having agility in a ton of clothing and pads doesn't seem to bother me at all. and I stay warm the whole time and watch my opponents freeze.
also the ball I keep in my jacket pocket warms up pretty fast and makes for one heck of a kicker on my second serve when the rest of the time the balls are quickly going dead in the cold.
