Using your Roux by Pininfarina karting helmet is easy. First, select the right size using the sizing chart. Put on the helmet and adjust it to fit snugly on your head. Make sure the visor is clean before each use. When you're in an emergency situation, the safety crew can use the special release system to take off the helmet quickly. Always keep your helmet in the provided box when not in use to protect it from damage. Clean the visor shields regularly with a soft cloth and mild cleaner. Check the gasket seal for any signs of wear and replace it if necessary. Remember, your safety is the most important thing, so always wear your helmet properly when karting.
