Your helmet’s lifespan
We recommend replacing your helmet five years after its date of manufacture, which you can find on the label inside the helmet. Because damage isn’t always visible, any helmet involved in a crash or impact should be discarded and replaced. Avoid using solvents or other harsh products, as they can reduce the helmet’s effectiveness.

All B’TWIN helmets are first tested in our lab in Lille to ensure safety before being tried in real-world riding conditions.
EN 1078 CERTIFIED
This helmet complies with EN 1078, the European standard for cycling, skating, scootering and skateboarding helmets. The standard sets strict requirements for construction, field of vision, shock absorption, strap strength and resistance to penetration.
Approved by UTAC
B’TWIN helmets are also approved by UTAC, an independent laboratory accredited by COFRAC (the French Accreditation Committee).
