Merino wool naturally provides superior warmth without bulk, even when wet. It regulates temperature by transporting sweat and moisture away from skin while providing cozy, quick drying, anti-microbial insulation. We blended this famously soft fiber with just enough spandex for excellent fit and shape retention. Kerrit Sticks™ Silicone knee patches, quick-access side pockets and slimming flatlock seams make this a flattering, functional tight for chilly days across the country and the calendar.
