1.2.6 Badges & Embroidery, the attachment of badges and use of embroidery on competitor’s overalls can have a detrimental effect on the protection afforded by the garment. Where this is done please refer to standard for that covers the apparel and or manufacturer’s requirements.
Each helmet should be chosen to fit the user’s head and the intended use. Each helmet tends to mould to the shape of the user’s head over time and should not be repeatedly shared. Helmets must not be modified, except in accordance with the manufacturer’s guidelines. Painting of helmets, particularly those with a polycarbonate shell, may weaken the structure, as may the application of non-approved stickers. If air vents or communication equipment are required, consideration should be given to purchasing a helmet to meet those requirements. The use of speakers mounted in helmets, other than those supplied by the helmet manufacturer, is prohibited. Helmets must extend to cover the complete ear. “Skull Cap” style helmets must not be used
