Thermal clothes are excellent at insulating and keeping your body’s heat in while absorbing and evaporating your sweat. Thermal base layers can be worn under your normal clothes during the day and also to bed. K2 Base Camp has something for your next outdoor trip whether you’re looking for thermal base layers with the right stretch, breathability, or comfort.

How thermals should fit on your body

We say, “snug is best”. Finding the right fit for your body is essential for your thermals to provide you the ideal warmth and comfort for your activities. Your thermal base layers should sit close to your skin so there are no gaps but not feel tight. This will prevent any cold air to breeze in and allow the fabric to properly trap heat and wick moisture away from the skin.
