If your sled has a battery you have a 12 volt dc electrical system which will support Gerbings. com electric gloves which are the warmest make sure your list also includes a thermosat otherwise you will cook your hands. If your sled does not have a battery then you would need a rectifier to get a DC electrical output to tap into. There are other brands of electrical gloves out there but Gerbings are the best. I have gone total electric with jacket liner and pants liners and have riden in 30 below weather and have it feel like spring. Just a turn of the dial and you can be as warm as toast. You can mess around with all kinds of other stuff but this is the only way to go. I have a whole bunch of gloves and liners and long johns, sweaters, fleece tops & bottoms etc., you can have it all, if you want it, don't use any of it any more.
