It was purchased to replace the previous model of the company, the IS-17, after 4 years of daily use. I was satisfied with the previous model and preferred to buy the one that replaced it. However, in reality, what replaced the previous model is the C70, and the i70 is the next one with a small price difference. While it cost me the same amount of money as the IS-17, it has some improvements such as better ventilation, a better and more convenient button to lower the sun visor, and better quality padding. I recommend it as an economical solution that still provides sufficient protection. I use it for scooters and street motorcycles. It has received 4 stars in the sharp test, while the previous model had 5 stars. Check it out at the following link:

My previous two helmets were in the range of 90 euros (Caberg, Vester), and I consider this one at 170 euros worth its money since it also comes with a pinlock. I used to wear size M, but I got size S for this one, which has the same shell with different padding. It has very good peripheral visibility and the internal tinted sun visor is quite good. The padding inside is removable and you can also change the size by adjusting only the top or bottom part for an even better fit. It has fabric under the chin to cut the wind. The visor has a notch before fully closing for city riding, where you often raise and lower it to let air in, but it doesn't do much. I don't know if it's my position or the height of the visor on the bike, but the wind hits the helmet and it creates some noise. Overall, I am satisfied.
