Interesting but can 10w of power really heat you up that much?

When I used to ride all year round. I found it was never my core that was cold.
More the fingers and toes and neck.
And you need your digits to control the bike effectively.
I found heated grips helped but again only on the palm of your hand rather than the fingers.

I'm just glad I no longer have to hardcore it like that. But I do miss being a more competent rider.
