The Kari Traa Tirill Tights are functional women’s training leggings. They’re this year’s warmest and have water-repellent material on the front thigh to deal with winter weather. Silicone grip on the ankle holds the pant leg in place, while a crotch gusset and 4-way stretch properties won’t restrict how you move. The warm, quick-drying material is brushed inside with flatlock seams for non-chafing smoothness. So slip them on.
