Right there. I can't wear ski gloves without hands becoming soaked.
My winter rides in the teens (f) i ride a bike with regular pedals and hiking boots with Goretex. Never ever had cold feet.
My latest on gloves is 3 pairs of the cheap brown jersey gloves with a disposable hand warmer outside the first inside glove.
