Saturday me and a friend went out on our 4 wheelers (well my 4 wheeler and his 6) and it was -10 degrees. We both had heavy winter mitts on and still our hands and thumbs got pretty cold. We've been thinking about heated grips for awhile, but after that we both feel it's a must. How many of you have heated grips and thumb warmers? And if so what brand did you go with? I'm looking at the Symtec Heat Demons that, although a bit spendy, seem to get good reviews.
