My wife Too!
We love to tour and that means time on the sled,over the years we have found only one thing that really works. Fleece lined gauntlets with thinner gloves. The reason for thinner gloves is to get more warmth to the fingers, thick gloves hold back to much of the heat. Cost for the guantlets 50.00 dollars, happy wife PRICELESS an I get to sled! We purchased the one's with the round hoop as they make it easy to get your hands in. Happy Wifes mean Happy Trails!!!
