Heated grips

[Fazerjon]

Oxford Heated grips every time, I've put them on every bike I've owned over the years, easy to fit, reliable and get hot enough to keep your hands nice and warm. My only gripe is with any heated grips is the tips of my thumbs get cold as they face the cold air directly.
Best grips in my opinion is the Oxford Premium Touring ones, you can get them on eBay for around £45, but the price creeps up as winter closes in....
Can't comment on the heated mits, not tried them.
