What Our Gearhead® Experts Are Saying: "This shirt looks like an everyday tee but performs like a full-on training top. It’s breathable, dries fast, and doesn’t get clingy—perfect for running, hiking, or hot-weather travel." For hot days on the move or quick training sessions before sundown, we reach for the Roark Mathis Active Short-Sleeve Shirt. Built with lightweight DriRelease® jersey knit, this shirt dries four times faster than standard cotton, helping regulate temperature and keep us cool as the pace picks up. It feels soft and familiar, like our favorite cotton tee, but offers the tech we need to stay comfortable when things heat up. With its classic cut and breathable performance, the Mathis Active tee seamlessly moves from early runs to afternoon hangs—no outfit swap required. This shirt is proof we don’t need to compromise style for function when we’re living life in motion.
