My Gerbings T5 gloves did great in the rain this past weekend and have for the last three years. Between the leathers, heated vest and the gloves, I was very comfortable in the cold weather well below 45 dg.
Not sure I understand about the comments that they would degrade from being in the rain, but maybe I'm missing some detail. Besides, Gerbing will replace any of their products for any reason, no matter where purchased, if found to be defective.
(Provided it wasn't road rash or abuse.)
Hand's down, the best heated clothing on the market.
