Designed for game day, the gym and outdoor training, the Nike Pro HyperWarm Men's Training Tights are the warmest of our Nike Pro collection. They feature thermal fabric for added warmth, sweat-wicking material and mesh panels to keep you comfortable in any workout. OPTIMAL BREATHABILITY Durable mesh panels provide targeted ventilation to help keep you cool and comfortable when your workout heats up. An updated waistband provides a buffer between the fabric and your skin for added airflow and cooling. FOCUSED MOVEMENT A snug elastic waistband holds the tights in place while four-way stretch fabric and flat seams allow you to move freely in any direction.
