I give it three stars because I have changed four helmets, 3 extra large, and this one was a bit tight for me! There is no problem, I will open it by placing an object to make it open a little to the right and left in length, there is no problem. It makes an annoying noise from 80 to 100 km, but it is not deafening, just a little annoying. But there is an issue with the visor for the sun, which gives you a feeling like wearing glasses with the wrong prescription, it distorts the image somewhat strangely, I can't give a better explanation! But it makes you a little dizzy!

For 108 euros, it offers a pinlock for applying an anti-fog membrane, a sun visor, and vents that seem capable of circulating enough air inside. Overall, it shows quality construction and its graphics are very nice and not elaborate. I bought it for use in the city with an on-off motorcycle. On the highway at high speeds, it produces noise from the air, but at tolerable levels. With the visor open, it makes noise, but that is logical. The sun visor is satisfactory and definitely helps to avoid squinting from the sun, although it is designed to accommodate glasses as well. However, the sun visor is not like sunglasses. Overall, it is a fair choice for its price.
