EN 1078 certified

European standard setting out the requirements and test methods for helmets to be worn by users of inline skates, skateboards, scooters and bicycles. The corresponding requirements and test methods cover the following aspects: construction, including field of vision; shock absorption properties, characteristics of the retention system, including the chinstrap and tightening devices; marking and information.

When should I replace my helmet?

We recommend replacing your helmet in 2 cases:

1/ After a fall
In the event of a fall, the material of your helmet 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 of your helmet degrades over time. It can deteriorate due to impact, where it is stored, the climate, and its use. We recommend replacing your helmet at least every 5 years

How do you adjust the helmet?

Follow these 2 quick steps to adjust your helmet in 5 minutes:

1/ Clip the 2 straps with the buckle: check that you can still slide 2 fingers between the strap and your chin.

2/ Adjust the straps so that they form a "Y" on each side of your ears. Just below the ear.

The helmet should be in contact with your head, without tipping forward, backward, or sideways, even when you're moving.
