Men's thermal underwear | Base Layer

The main purpose of thermal underwear or a base layer is to manage the moisture produced by the body. This base layer helps eliminate perspiration and, depending on the type of physical activity, it must also provide warmth or keep you cool.

To be effective, it should be snug without being too tight, allowing moisture to be transported to the outside while retaining heat. A base layer should provide effective odor protection and also keep you warm and dry.
