The T.K.O. Mechanism Jersey features a low-cut collar to reduce chafing and improve the comfort of the jersey. It gives the jersey a modern look and aerodynamic benefits - a jersey using lightweight fabric that provides everything you need for competitive races or fast-paced training days. Still remains a staple for your everyday summer rides. The concealed single-layer patch side pocket is fitted with a stay-down seam zipper. A pocket that makes it easy to reach your essentials.
