When I received the helmet and was inspecting it I found that the cheek pad retainers on both cheek pads had come loose from the helmet. This was a little disappointing. I contacted Suomy and they offered to repair the helmet. They also suggested the type of glue to use so that I could do the repair. I did the simple repair instead of returning the helmet. Everthing else looked very good. The chin guard release works very well and locks in place, no rattles or vibration. The vent levers are easy to operate with or without gloves. The air flow seems to be no better or worse then other brands of helmets. The sun visor lever also works very easy with or without gloves. Although the visor needs to move about one-half inch lower when in the down position as there is a gap at the bottom of the visor and the bottom edge of the visor is right in the line of sight when looking down at the speedometer. The helmet has a snug fit but is not too tight. My head measures 22-3/8" and I ordered a medium size. It is very comfortable and well made. The weight is slightly more then some helmets and can be noticed after a few hours. The quick release chin strap is great. I wish that all of my helmets had it. It is a very well made helmet.
