I have owned five CS-5N helmets in recent years. One held up remarkably well a couple of years ago and no doubt saved me from a serious head injury. These helmets are so comfortable that they are my default helmet most days. I have used the helmet between 27F and 106F. The two vents are nice at higher temperatures; Cooler temperatures just add a watch cap. The fit, finish and color choices are great. This HJC helmet is a tremendous value and shipping has always been highly satisfactory. Sizes are always right on.
Great value, chin strap could be a bit longer, not much left to get threw the rings. Visor function works well. While I use transition sunglasses from time to time, I use the visor while pointed into the suns glare. Also found the visor great when encountering rain as it deflects water off your face.
Overall this a a good modular at a good price.
The 'cut out' behind the lining for intercom speakers is a nice fit for my Sena speakers, I can hardly tell they are there.
The air flow is a bit lacking. I find myself lifting the face shield a little on hot and humid days. The sun shield could be darker on the top half. 2 strips of black electrical tape to the top of the sun shield blocks the sun light well.
I would buy this one again
