Built with climacool technology, the adidas Own The Run LS Tee is highly breathable, allowing air to circulate close to the skin helps to keep you cool as your workout heats up. The regular fit of the tee sits close to the body for a semi-fitted feel while still allowing for a full range of movement. Long sleeves & thumbholes provide extra coverage & help the sleeves stay locked in place, while 360-degree reflectivity ensures you stay seen in low lighting conditions.
