A base layer is essential to having a great outdoor experience during the colder months and especially in winter, whether you are skiing at your favorite resort, heading to the Annapurna camp base, or hunting in the arctic wilderness. Base layer garments include tops, pants, and underwear. These clothes are designed to keep you dry and warm, ensuring comfort and peak performance in all outdoor activities. This first layer of thermal wear works together with mid and outer layers to remove moisture and provide resistance to cold, snow, rain, and wind. Together, the three layers ensure proper thermal insulation and comfort even during prolonged exposure to harsh weather.
Compared to tops and pants, underwear has a few distinct characteristics. Like its siblings, it must ensure moisture wicking and regulate the temperature of the body, but it also needs to meet specific hygienic standards. Besides, compared to other first layer garments, underwear is more versatile and can be used in many situations other than outdoor sports activities. Typical materials used include Merino wool and polyester blends, meeting different needs and tastes. For an extensive selection of quality base layer underwear, surf our online catalog. We offer products made by top-ranking companies that go to great lengths to ensure their apparel meets or exceeds the standards set for the category.
