Product Customer Reviews

Not very pleasant to wear!!!
Nice look. Seems reliable. A little expensive...
comfortable good protection
Good helmet,
Very good product, light and adjustable. The earbuds are great for mornings and as they are detachable, there is no problem of discomfort when temperatures are higher.
Compliant
Comfortable headset within reach
Alright
This helmet follows me everywhere during my bike trips. Only downside: as soon as you pick up speed, it creates noise in the helmet
The helmet tends to tilt forward (when you pedal) because of the strap/adjustment wheel which is positioned too low on the neck: by mechanical effect when you raise your head to look at the road the helmet “tips” forward and down onto the front. Which causes a discomfort.

Alright
Great product
I am very dissatisfied with this helmet which is uncomfortable and even dangerous. Firstly, the helmet is uncomfortable and the adjustment ineffective. There is little ventilation, so you feel like you're suffocating when you cycle for several kilometers or when it's hot. The strap adjustment does not hold and loosens on its own. You might think that this is not very problematic when in reality it is dangerous because once loosened, when there is a shake, it can be placed in a bad position on the head and be too far back or too on the side. This forces me to stop in the middle of the road to reposition it. I strongly advise against this helmet.

Sizes
If you're between sizes, choose the bigger size.Choosing the right-sized helmet and getting the fit right is essential. For children, never buy a helmet that is too big on the assumption that they will grow.M: 21.7” - 23.2”L: 23.2” - 24.4”
Adjustment
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.
