The Mission VaporActive Ion Training Short gives you the ultimate freedom to move. Fitted with overlapping curved hems, side vents and a 4 inch inseam, it's ideal for any workout, training or team sport. A drawstring waist customizes the fit to your body. Flatlock stitching for zero chafing. VaporActive, powered by patented 37.5 technology, attracts and rapidly evaporates sweat so you can dry faster and go longer. Permanently embedded at the fiber level, the ultra-fast drying technology never degrades or washes out. Active particles in the fibers attract and trap odor-causing molecules, later releasing them in the laundry. UPF 50. Care instructions: machine wash cold with like colors. Only non-chlorine bleach when needed. Do not use softeners. Tumble dry low. Do not iron.
