Light visible comfort, the light hangs at the back very well. Excellent for safety. 4 years ago, if I hadn't worn a helmet during a fall, I wouldn't be here to RECOMMEND you WEAR A HELMET and change models regularly.

Straps too fragile

Purchased at the start of 2020, I used it de facto 3 years (2020 in confinement + teleworking all year round) 3 or 4 times per week. Not much to complain about EXCEPT the straps which are TOO FRAGILE: in the last 2 months, 2 straps have deteriorated to the point of tearing (one at the clip buckle, and one at one of the side adjustment buckles) . Unusable headset. Given the increase in prices, I am hesitant to change brands...

suitable for a teenager

If you're 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: 20.9” – 22.8”L: 22” – 24”


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.

We recommend that you try on different sizes to find the best fit.
