Taking inspiration from the Pro Series one piece, the CPX-C jacket is fitted with the same carbon shoulder sliders and race hump and uses our profile race fit for a jacket that’s supremely comfortable on sports bikes. - RST profile race fit: specifically designed to be comfortable and easy to move in on sports bikes with an aggressive riding position. - Full grain 1.1-1.3mm cowhide: soft and supple whilst retaining excellent abrasion and tear resistance properties. - Triple and double stitched seams: all seams are stitched using super-strong bonded nylon for maximum burst resistance. - Contour plus level 1 back protector fitted as standard, with contour plus CE armour to shoulders and elbows. - CPX-C carbon shoulder external sliders, with a lower co-efficient of friction to dissipate and redirect impact forces. - Large ventilated panels and removable thermal gilet for all season comfort.
