Women's base layers | Thermal underwear

The primary mission of a base layer or thermal underwear is to effectively manage the moisture produced by the body. This first layer helps wick away sweat while keeping you in ideal conditions—whether you need warmth or cooling—depending on the activity you are practicing.

Why choose a form-fitting base layer?

A base layer must be form-fitting without being too tight to be truly effective. It needs to move moisture outward while retaining your body heat. A well-designed fit ensures optimal moisture management and long-lasting comfort.

Essential features of a good base layer

A quality base layer should meet several essential criteria:

  • Odor protection: Stay fresh longer during exercise.
  • Warmth and dryness: It should keep your body warm while wicking away moisture, ensuring you stay dry even after intense effort.
