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.

Return conditions for personal protective equipment

Make sure that this product fits properly. If you do need to return it, you will need to make sure it still has with the instructions, labels, and if applicable, original packaging. Conditions: https://tinyurl.com/4jdc584f

How do you adjust the helmet?

3 quick steps for adjusting your helmet in 2 minutes: 1/ If needed, pull your ponytail through the back of the helmet (lower the dial's rim). 2/ Adjust and clip the buckles on the 2 straps: check that you can still slide 2 fingers between the strap and your chin. 3/ Adjust the tightness around your head using the rear dial. The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.

How do you choose your mountain bike helmet size?

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.
