When should I replace my helmet?
We recommend replacing your helmet in 2 cases: 1/ After a fall: In the event of a fall, your helmet's material can deteriorate or even break. Sometimes, you won't even notice. That is why we recommend replacing it if you have the slightest doubt. 2/After 5 years of use: The foam deteriorates. It can deteriorate due to impact, where it is stored, the climate, and its use. We therefore recommend replacing your helmet at least every 5 years.
