INTRAKNIT THERMAL MERINO. Ideal for cool to cold weather, this lightweight 3D-knit with Merino Sport yarn offers gender-specific ventillation to maximize thermoregulation and breathability during high-intensity, sweat-inducing activites.

WHY MERINO WOOL? Thinner and softer than regular wool, it's easy to wear next to skin. Each fiber transports sweat away as a vapor (we tested it ourselves) and regulates body temperature to keep you cool in summer and warm in winter. FUNCTIONAL FEATURES.
