The optional upgrade of the Knox chest protector is courtesy of a low-profile Micro-Lock chest insert, designed to fit all Knox Armoured Shirts and Jackets via the VELCRO® strip. The Knox Micro-Lock chest protector offers a snug and soft-feel fit to the wearer, but thanks to its smart technology it locks in the case of an impact and absorbs a significant amount of energy before it gets to the wearer’s torso. It features a breathable, perforated design that is great for ventilation, and the removable soft mesh cover is washable to allow for fresh year-round wear. Available for both men and women's motorcycle apparel, they are CE Certified as a Level 1 protector.
