8 years ago I ski'd at Jasper in the northern Canadian Rockies in mid-Jan. It was cheap for a reason! -38c in the day! We had to whether masks to cover nose and mouth to prevent them becoming frosted or frost bitten. The cold was really dry, and when wrapped up in ski gear and exercising, you didn't feel it. But stop for any period, you can feel it creeping in. You didn't want to expose skin for any more than 10 mins. As an example, a friend fell and split his goggles. They them steamed up, so he took them off to be able to see. It took around 15 mins to get the mid-mountain lodge, and he had to sit in front of the log fire for 15 mins. to unfrost his glasses from his face. Great holiday, best powder skiing ever. Recommend to anyone. Just remembered there was a roof top jacuzzi on the hotel. You had to leep from the door into it. If you touched the metal railing instand frosting to it (so I heard). Love any excuse to talk skiing war stories.
