I have Eska gloves and use them without heated grips and they've been great the last few days! Really recommend them! http://www.motolegends.com/gloves/eska-pilot-gtx-gloves.html
I had keis heated gloves & waist jacket, but I only work 14 mile from my house & I just couldnt be bothered to connect up all that wiring so I sold it all on ebay & brought some triumph heated grips....Tis true tho, last week when it was well below freezing just after midnight, my thumbs were cold & I kept putting them out of direct wind. I also found the keis gloves were a little bulky....But boy did they keep your hands warm. As for the heated waistcoat/jacket, I found that as the heat patches were next to the kidneys, if I had them too warm it made me feel nauseous. Thin layers that what you need, not one big jumper & a jacket.
