Stay warm on the trail in these tights. A wind-resistant overlay on the front blocks the wind for added warmth while the back allows your body to ventilate. The pre-shaped knees and built-in stretch ensure a natural range of motion for running, hiking or cross-country skiing. Ankle zips make them easy to pull on and off over shoes. adidas Agravic Womens Trail Running Leggings Fitness Sports Reflective Black
