Sleds have heated handles, so that makes a difference. Snowmobile gloves should work, but even a well insulated work glove can work. If you ride high speed, you should get either hand guards or perhaps a gauntlet type thing that will help keep your hands warm. You can probably also purchase aftermarket hand warmers for atvs if you do much cold weather riding. I do some snowplowing with my atv, and good work gloves do the trick, but it's not high speed.
