WATER-REPELLENT MILES. Enjoy those wet weather miles with the Nike Repel Challenger Tights. We used runner data to place water-repellent fabric on a favorite design, helping to make sure you keep after it even when the rain arrives. Smooth and stretchy, the tights offer up 2 additional pockets so you can stash a key or card. Designed With Data We used athlete data to learn where water impacts runners the most. Using that data, we placed knit, water-repellent fabric throughout to help keep you dry. It feels soft with a little bit of stretch, so you can keep moving freely through your stride. Easy On, Easy Off Elongated ankle zippers let you customize your airflow. They also make it easy to take off the tights over your shoes. Stash Your Essentials A drop-in pocket at the center back lets you stash a key or card. An additional pocket at the hip adds even more storage. More Benefits An encased elastic waistband with an external drawcord lets you adjust the fit. Product Details Tight fit for a body-hugging feel 85% polyester/15% spandex Machine wash Imported
