My hands and feet were never cold on Denali

"My hands and feet were never cold on Denali. I wore the Insulator Boot Liners at 14,000 feet and above and, although the air temperature was rarely below -20F, we believe that the blue ice that we were climbing on frequently was around -30F or below. Only after standing around for a long time would I even notice the cold ,but as soon as I started moving again, I'd be toasty warm. The Vapor Mitts were so warm that I actually had to take them off when I was working hard. But when the wind came and I shoved my hands inside the mitts, they gave me the same feeling of confidence and protection as my down jacket".
