The ‘onion principle’, also known as layering, is widely used by winter sportsmen, adventurers, anglers and hunters, and anyone practicing outdoor activities. The underlying idea is to coordinate various layers of clothing to get the most in terms of comfort and performance. In a nutshell, it means staying comfortable regardless of the weather and achieving your goal without freezing or feeling too hot. The ideal thermal wear consists of three layers, each with specific characteristics and interacting with the others to ensure optimal body temperature and moisture wicking properties. The grounding of the layering system is the first, or base layer that is in direct contact with the skin.
When choosing a base layer, consider three aspects: fabrics, weight, and fit. Typically, there are synthetic or Merino wool materials used. Both types provide quality performance in terms of removing moisture and retaining heat. Hence, the choice is personal. The weight depends on the outdoor conditions and how your body reacts to cold temperatures, sweat, etc. The fit is essential. The layer should adhere to the skin without being too tight. We provide a vast assortment of top-notch base layers, including tops, pants, and underwear designed by leading companies and offered at affordable prices.
