Practical helmet

A beautiful and comfortable bicycle helmet. Only the sizes are a bit on the small side. Satisfied customer

Hurtful straps

The straps hurt my face and irritate me. It's a shame because apart from that it's light, airy, pretty, and easy to adjust. I also regret that there is no provision for sliding tied up long hair.

Unbeatable quality/price ratio

Perfect helmet for the price, not too heavy you forget it quite quickly, adjusts easily and even if I would have preferred a slightly more qualitative closure (and not red...) it does the job. And once again, for the price it's hard to do better. I don't use the attachments for Decathlon lights but they exist.

OK but...

Despite advice on choosing the size and a discussion to choose the best one, I found the helmet quite uncomfortable, it squeezed certain parts of my head in a very unpleasant way without the adjustments being able to do anything about it. So I'm a little mixed on this product.

No luck with this headset, the adjustment no longer works and it's still 36 euros to take back to the store to see, perhaps a commercial gesture

If you ftre between sizes, choose the bigger size.Choosing the right-sized helmet and getting the fit right is essential. For kids, never buy a helmet that is too big on the assumption that they will grow.M: 20.9Inch – 22.8InchL: 22Inch – 24Inch


For maximum protection, the helmet should be in close contact with your head, and the fastening system must always be correctly adjusted without being too tight around your forehead. When the straps are properly adjusted, the helmet should not slide forward, back, or sideways. For this reason, there are several sizes available. We recommend that you try on different sizes to find the best fit.
