How long are ski helmets good for?

The lifespan of a ski helmet can vary, but the general recommendation is to replace your helmet every 5 to 7 years, even if it appears undamaged. Over time, the materials used in the helmet may degrade or become less effective at protecting your head. Additionally, if the helmet sustains a significant impact or if you notice any cracks or damage, it is important to replace it immediately, as it may not provide adequate protection anymore. It is essential to check the manufacturer's recommendations for your specific helmet model, as they might specify a different lifespan or maintenance requirements.
