Overall Fitting Is Good But Not Orange

The helmet's fitting is well , it's straps are good and I loved the magnetic lock for straps. But, its colour is not as shown in the pictures. It is more like a neon/bright pinkinsh orange . So, I didn't took this seriously but you should've kept the colour as it is! Rest is fine 😉

When should you replace a helmet?

Helmets are designed to protect your head from an impact. From just one impact. If you fall, you should replace the helmet even if it doesn't seem like the helmet is damaged: it could be weakened or cracked in invisible places... and thus no longer provide protection.We recommend replacing your helmet every 5 years, as some materials begin to age, particularly if the helmet is stored in a cold and/or wet place. (the production date is printed inside the helmet).

What does the en 1078 standard cover?

EN1078 is a European standard concerning the test methods and requirements for cycling, skateboarding and skating helmets.This standard covers the following aspects: construction, including field of vision; shock-absorbing properties; fastening system features, including the chinstrap and tightening systems; markings and information.

Terms and conditions for returns of personal protective equipment
