Why Is Moisture Management Critical for Ski Touring Base Layers?
The underlying mechanism involves the properties of the materials used in base layers. Fabrics designed for moisture-wicking, such as polyester and merino wool, draw perspiration away from the skin, allowing it to evaporate quickly while keeping the body dry. When moisture remains trapped against the skin, it can lead to a drop in body temperature as sweat cools, increasing the risk of hypothermia and reducing performance efficiency (Gonzalez et al., 2020). Thus, the choice of the best base layer for ski touring hinges on its ability to manage moisture, ensuring that skiers maintain optimal body temperature and comfort throughout their adventures.
