Mathis Short Sleeve Tee RUN AMOK x Black Sabbath Rock & Roll runs through our veins. Never failing to get us on our feet, the adrenaline pumping tracks expel a magnetism that connects every walk of life. It comes with great excitement that we present our collaboration with the pioneers of heavy metal: Black Sabbath. The Mathis is designed to deliver the performance required for a trail run or workout, while maintaining the styling of your graphic tee. Constructed from a lightweight DriRelease® Jersey Knit, the shirt regulates skin temperature and dries 4x faster than your typical cotton tee.
