Usage recommendations

Choose the correct size by measuring head circumference and comparing it with the manufacturer’s size guide. Clean the helmet with mild soap and water; avoid solvents or strong detergents. Store the helmet away from direct sunlight and extreme heat to preserve materials and fit. Replace the helmet after a crash or when padding and retention components show wear.
