I get cold hands on my VFR. I used my heated grips in Utah in September. When riding in and about 5 degrees C, with my grips (Oxford Heaterz) on max heat, my hands are okay, but my thumbs go numb. Ever tried riding with your thumbs on the same side of the grips as your fingers? Not a great idea, but somewhat warmer.
And today, while searching for something else, I found this: knucklewarmers.
They look like they come from Washington State, and I wonder if anyone has any experience with them, or with the company.
