The SmartWool Training Beanie provides great thermoregulation and moisture-management qualities, keeping you comfortable whilst exercising. Merino wool is a natural fabric, and is great for regulating your body temperature and heart rate due to its natural breathability and moisture-management properties. This happens easily when wearing the natural wool in comparison to a synthetic fibre. The SmartWool Training Beanie wicks sweat away from the body to keep you dry, and also traps air in its fibres to keep you warm. The beanie is lightweight, creating warmth without adding bulk for a more comfortable fit. Flat-lock seams create a smoother fit, reducing the chafing that can occur whilst exercising.
