When you drop into a trail full of gnarly rock drops and steep chutes, it's always nice to have some protection to give you a little extra peace of mind. Fortunately, Race Face has your back, and your chest... and your shoulders with the Flank Core Protection system. This lightweight and breathable core protector sits comfortably under your favorite jersey and fits like a second skin, keeping the targeted protection in it's place so it doesn't slide around in the event of a crash. High performance D3O shock-absorbing foam is found at the shoulders and spine, along with a custom heat-molded foam chest piece to protect your sternum area. A durable mesh main fabric allows for maximum venting, and features lycra stretch panels and flatlock seams to ensure mobility and comfort through your entire range of motion.
