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.

Cushioning foam

A cushioning foam replacement kit is available for this helmet on our website. Please note that on some helmets, the colour of the EVA cushioning foam (in contact with the top of the head) may vary.

When should I replace my helmet?

We recommend replacing your helmet in these two 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’s why we recommend replacing it if you have the slightest doubt. 2. After five years of use: The foam deteriorates. It can deteriorate due to impact, storage location, the climate, and its use. We therefore recommend replacing your helmet at least every five years.

How do you adjust the helmet?

Three easy steps for adjusting your helmet in two minutes: 1. If necessary, pull your ponytail through the back of the helmet (lower the dial’s rim). 2. Clip the straps together with the buckle and adjust: make sure you can slide two 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.
