Featuring X-VENT fabric technology and a lightweight mesh back panel, the 2XU Aero Tee promotes easy ventilation to keep you cool on long hot runs. A double-knit moisture-wicking main panel quickly transports moisture away from the skin for rapid moisture management and reflective logos and trims on the front, arms and back work to keep you visible in low lighting conditions. Care Instructions Machine wash in cold water with like colours. Do not tumble dry. Hang to dry in a cool shady area away from sun. Do not use bleach, fabric softeners or dryer sheets. Do not iron.
