Mountain climbing demands a lot from your body. One of the biggest challenges in cold environments is regulating your body temperature, which is critical for optimum performance. The best way to stabilize your temperature is through layering. Layering allows you to:
a. Manage body temperature efficiently
b. Minimize sweat
c. Insulate from the cold
d. Protect from wind, rain, snow
Shed a Layer - If you are comfortable when standing still, you will overheat quickly once you start climbing.
Keep Cool - If possible, avoid sweating. Once your layers get wet it is difficult to dry them out during a day of activity.
Regulate Your Temperature - Climbing efficiently is directly related to how hot or cold your body is running. Taking the time to shed or add a layer will improve your climb.
Layer Up at Rest Breaks - Quickly throw on a jacket or your parka at a break to trap the heat you generated climbing.
