Women’s Base layers are designed to move excess moisture away from your skin and keep you dry and comfortable.
This process is called wicking and is an essential part of any base layer system. Synthetic women’s base layers use capillary action to draw sweat away from the skin allowing evaporative cooling. Merino women’s base layers use natural fine-grade wool to achieve the same thing.
Merino base layers for women are particularly effective as women’s thermal underwear in the cool or cold conditions found when snowboarding. It is especially important for women’s winter thermals to have excellent performance properties because sweat can be very uncomfortable when it cools during inactive phases. Therefore avoid cotton women’s base layers at all costs – they will hold sweat next to your skin, leaving you feeling clammy while you’re hot and then cooling rapidly when you stop.
