Check out the Snowmobile gear suppliers. Chapparral, Dennis Kirk and a few other places supply the sled guys with killer winter gear. They basically wear the same type of stuff ATVers ride except its geared for cold weather. One thing that would make a big difference is get a full face helmet and something to keep your neck warm. If you dont want to spend that kind of cash at least make sure the vents on your helmet are closed! hehe
