I'm an old fart and my circulation isn't what it should be, so I have a problem with heated grips. In order to get the enough heat to transfer to my hands I have to keep a firm grip which tends to effect the circulation sort of a catch 22.
To get the blood flowing I need to relax and when I do of course I lose the heat transfer.
Heated gloves are the way to go for me.
