Go the distance. The Mission VaporActive Stratus Short Sleeve Running T-Shirt targeted mesh construction cools down your body's hot spots. Semi-fitted design with a drop hem, V-neck and mesh paneling combine with flat-lock stitching for zero chafing and reflective detailing for low light conditions to make this shirt the ultimate in performance, style and safety. Tailored to a runner's body, the drop hem skims the hips. UPF 50. VaporActive, powered by patented 37.5 technology, attracts and rapidly evaporates sweat so you can dry faster, stay cooler and go longer. The ultra-fast drying technology is chemical free and permanently embedded at the fiber level, so it will never degrade or wash out. Active particles in the fibers attract and trap odor-causing molecules, later releasing them in the laundry. Machine wash cold with like colors. Only non-chlorine bleach when needed. Do not use softeners. Tumble dry low. Do not iron.
