EQUIP YOURSELF WITH PROFESSIONAL WEATHER PROTECTION. Cold is just another challenge that needs to be overcome. We designed the Nike Storm-FIT ADV Run Division pants for just that challenge. It features a weatherproof design to protect you in harsh weather. We studied data from runners and placed zippered slits on the upper and lower legs so you can control your temperature. The system is designed for cold weather and can be worn alone or as a layer. Versatile performance The Run Division collection returns to brave the cold months. Based on technical details developed by our Advanced Running Concepts (ARC) team, we created a design that can be worn alone or as a layer. The lightweight design means they can be worn anytime - before, during or after your run. The cold months mean darkness. That's why we added reflective tape to each leg. Brave the elements Nike Storm-FIT ADV technology combines wind- and waterproof fabric with advanced construction and technical features to keep you comfortable in harsh weather. The hems are fully sealed to keep the elements out. Personalize Air Circulation. Using body mapping studies of athletes, we identified the areas where air circulation is needed most. We placed zippered slots on the upper and lower legs so you can adjust airflow during your run. Secure feel Cuffed hems provide a secure fit and keep water out. Elastic waistband with drawcord allows for an adjustable fit. Side pockets are suitable for storing small items. A pocket in the center back allows you to store your smartphone.x16
