Our Nine Trails running top excels at shifting gears throughout the day. The trail-worthy 100% polyester spun jersey fabric wicks moisture, breathes freely and dries rapidly—but looks and feels like cotton. The combination of comfort and technical performance yields everyday versatility, complemented by details like set-in sleeves with underarm gussets for chafe-free range of motion. With Polygiene® permanent odor control, no tags for no itch, and a locker loop to let it dry until tomorrow. Reflective logo on the left chest keeps you visible.
