POC helmets are made of advanced materials that provide maximum protection. Do not expose your helmet to impact or external force during transport. Store it in a dry place, away from any source of heat like a hot radiator or sunshine through a car window. Clean the helmet with a damp cloth and perhaps a little mild liquid soap. Do not use strong detergents or solvents. Decals, glue etc. may reduce durability. Helmets are ”perishables” that should be replaced after three years of use. If you know or suspect that your helmet has been damaged or exposed to any abnormal force, you should have it carefully checked by an authorized POC dealer. You can also send or bring it into POC for inspection. Damage that may reduce your helmet’s protective qualities can be invisible and difficult to detect. Replace the helmet if there is any sign or suspicion of damage.
