I wear Descente Weather Warriors with a good, thin wool liner.
Sometimes my thumbs and finger tips become agonizingly cold and at other times they don't.
I think it has something to do with how my body manages its blood flow in cold conditions.
My son has suggested I put my gloves in the dryer on low setting prior to starting out in the morning.
On the few days I have tried that it has worked.
Hardly scientific, though, since I have had cold days and warm hands without pre-warming my gloves.
Next winter, I may go to pogies.
I have also seen an ad for something that goes on the wrist and supposedly tricks the body into sending blood to the finger tips, but I don't know enough about it.
