Hjc IS 17 Armada
They are very comfortable and more importantly very low noise, small carved bone to be careful carving to ask. The hull is real even more beautiful than photo, I've already done a few kilometers with no complaints. In my case what more I look into a helmet is your safety, this has 5 * sharp and noise and both perfect spots. The inner glasses are not the darkest I've seen but do their job 100% and are very easy to handle even with gloves.
