Introducing the Ultimateadidas Engineered Tee, the latest running t-shirt by adidas with knit structures that maximize ventilation and airflow where you heat up the most, so you always feel comfortable throughout your runs. The two-tone knit shows off its advanced technology, while AEROREADY keeps you dry and focused mile after mile. Reflective details include the performance logo, reflective bar, and reflective HEAT.RDY logo, that ensure you're seen even in low-light runs. 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.
