Long Sleeve Tech Wool men's - Royal blue

Long Sleeve Tech Wool is engineered for consistent comfort and performance in changing conditions. Built with an innovative dual-fabric construction that blends merino wool and 37.5® Technology, it offers advanced thermoregulation: the wool insulates naturally, while 37.5® particles react to your body heat – helping retain warmth or accelerate moisture evaporation. Sweat-prone zones at the sides and back feature lighter fabric to accelerate evaporation where it matters most. The result: reduced temperature swings, faster drying, and greater comfort during both high and low intensity efforts. A soft construction with articulates sleeves minimizes chafing and enhances freedom of movement, while reflective details increase visibility through darker runs. Made for athletes who train through every season – and demand more from every layer.
