I'm looking for some ideas on tweaking my Grips and Warmers on my sled. How many of you guys froze your hands off last year? I remember riding back to the truck at dusk. Temperature was -5 degrees F. I was riding my stock 07 M1 and had the thumb and hand warmers on Hi. For gloves I was wearing the Klim Klimate Gortex Gloves. My hands were dry and I don't remember my hands ever being so cold. On the way to the truck I traded my buddy sleds and rode his 800 RMK. His handwarmers were night and day hotter than mine. He often complains that his hands sweat when he leaves them on too long on Hi. What gives, did I get a lemon set of warmers or did any of you guys notice weak handwarmers?
