If you’re going to spend a day on the ski slopes or head out into the great outdoors during the colder time of the year, you need to wear the correct apparel. Thermal wear consists of three layers of clothing: for keeping the skin warm and dry, providing insulation, and ensuring water, wind, and cold resistance. Quality clothing makes the three layers work together to keep the body comfortable whatever the outdoor activity. Choosing the most suitable base layer for the intended use, weather conditions, and personal characteristics is crucial to ensuring peak performance and comfort.
It is even more true for the upper body, which tends to sweat more than the legs. Frequently used materials for first layer tops include Merino wool, polyester, spandex, and polypropylene. Overall, these are specialized garments featuring moisture wicking, quick-drying properties. A proper fit is crucial for decreasing chafing and ensuring the comfort of movement. The ultimate choice depends on personal taste. In our online catalog, you can find a broad selection of top-notch base layer tops at affordable prices. We cooperate with renowned brands, including Helly Hansen and Champion Tactical, to deliver tried and tested tops that ensure comfort, warmth, and performance at every latitude and in all weather conditions.
