Very nice quality helmet. Carbon fibre makes it extremely light so its nice for people with bad necks such as mine! Helmet fits a bit tight so you may have to take some break in time. With the vents closed there is very little wind noise! Although, there isnt much airflow with the vents open, but i didn't find it to got too hot inside the helmet. The pinlock works great and i havnt had any issue with fog yet. This is an excellent helmet for the price, and the lightness of carbon fibre makes it much better. I highly recommend this helmet.
