      Description

      Designed for bike rides lasting over 2 hours.

      How do you choose your mountain bike helmet size?

      To find your helmet size, simply measure your head circumference (around the forehead). This mountain bike helmet is available in three sizes: S: 52 - 55 cm M : 55 - 59 cm L: 59 - 62 cm

      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.
