Airfit feature is fantastic, really gets the helmet nice and snug on your head and it is easy to operate with your gloves on. Visor lock is a bit difficult to operate with gloves on but works even in a crash. I had a lowside at chuckwalla going CCW in turn 5 at about 85 MPH. Visor hit pavement first as I came off the bike. The visor neither came off or opened during the entirety of the crash. I don’t know exactly how many times I tumbled, but the helmet did its job admirably. The airfit and visor lock are great features for such an inexpensive helmet. I immediately replaced it with another one, and will be my go to racing helmet for the foreseeable future.
