Feel the rush of speed and endorphins as you log more miles than ever before. Engineered for maximum performance on your toughest runs, this adidas running t-shirt has HEAT.RDY to cool you down as you pick up your pace. Reflective details, including a 20cm long reflective bar at the back so soft that you don't even feel it, offer 360º reflectivity in low light conditions. By choosing recycled, we are able to reuse materials that have already been created, which helps to reduce waste and our reliance on finite resources.
