Active insulation describes jackets or other clothing layers which, due to their combination of warmth without weight and superior breathability, are perfectly suited to high output activity in cool and cold climates.

Polartec® Alpha™ is one of the main insulation types within this range due to its versatile, stand-alone material which limits the cold air that enters the garment while moving excess heat away from the body. As activity increases, so does moisture. Active insulation technology combats this by moving vapour away from the body before it can cause overheating and discomfort. Our active insulation range strikes a balance between breathable warmth, packability and comfort.
