Just thinking on my way in this morning with my heated steering wheel on, how come no heated golf grips? I have heated grips on my 4-wheeler, snow blower, truck, car, snowmobile and, a pair of heated gloves for hunting. I Googled that there is a expired patent for them but none ever brought to market. What do you cold weather golfers think? Battery operated with aa or aaa battery and small coil and contact switch that turns on when you grip it? By time you do your pre shot routine it would be warm and comfy.
