Smartwool Thermal Merino Wool Reversible Neck Gaiter Worn 1 Time Like New Condition WINTER WARMTH. Take on the cold confidently with this Smartwool Thermal Merino Wool Reversible Neck Gaiter. Keeping you warm and comfortable no matter the temperature, this gaiter features reversible construction for added versatility. CLASSIC THERMAL MERINO. Ideal for cold-weather activities where warmth and breathability are crucial, this midweight fabric used a 100% Merino wool construction that helps move moisture away from skin to keep you warm and dry. 10.25" (26.5 cm) length 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 warm in winter.
