The Nike Pro HyperCool Men's 3/4 Training Tights feature sweat-wicking fabric and mesh panels to help keep you cool and dry during your workout. Targeted Ventilation Strategically placed mesh fabric enhances breathability in high-heat zones. Heat Deflection A below-the-knee graphic deflects sunlight from your legs, helping you stay cool during outdoor training sessions. Dryer, Faster Dri-FIT Technology helps you stay dry and comfortable by wicking sweat away from your skin to the fabric's surface, where it quickly evaporates.
