The ultimate lightweight active shell, the Ultralight is designed to take the chill off a morning run or downhill cycling descent. It is constructed from a silky-soft lightweight fabric with a nonstick interior for an exceptionally smooth feel against your skin. LYCRA® bindings at the neck and cuffs prevent chafing and offer additional wind protection on particularly blustery days. Low-profile zippered side vents help you stay ventilated, while gripper tape on the interior hem prevents the back from riding up. The Ultralight offers a lightweight barrier to the cold and wind, but with a slimmer fit and a more refined aesthetic than a traditional windbreaker.
