Just had a ride out in 7 deg C and the Jet Road V2s are better than the GP Force, but maybe not as much as I hoped they would be.
Backs of the hands were pleasant down to the the first knuckle, but the ends of my fingers got very cold which was a slight disappointment, but not cold enough to impede movement or physically hurt, so definitely an improvement.
I guess this serves me right for being built like a racing snake and having hands like Montgomery Burns.
Given this is as cold as I'll ever ride and for no more than 45 mins, these will be fine. I'm sure above 10deg C they'll be ideal for longer rides, then I can use the GP Force in the summer when I'm trying to manage keeping the temps down.
