HJC Helmets Cly Chin Curtain - Motorcycle Wind Protection for Cold Weather Riding - Perfect for Touring, Cruising & Adventure Bikes

I bought this for the HJC CL-Y helmet, which has no cover whatsoever to shield from the wind going up into the helmet, and then into your eyes. I think this is super poor design, but it is the only helmet that carries my size so I don't have much of a choice. My previous helmet had a curtain already designed with the helmet, and it worked perfectly, keeping the wind out.So, I tried this chin curtain, hoping it would help with my new helmet. The idea is that this thing is just shoved into the chin part of the helmet, which makes sense conceptually. But in actuality, it doesn't do much. There's a plastic piece that runs along the top of this thing and its long enough so the ends can fit into the sides of the helmet. But it is far too flimsy and is bent too easily. While I installed it into my helmet, it bent the opposite way of its natural curve, and is now stuck that way, so the wind just goes straight through like it did before. Obviously, it can't do its job when it's not completely lined up with the curve of the chin part of the helmet.On top of this, it makes putting on the helmet more aggravating than ever, because it moves when the helmet goes over your head, and then it must be readjusted to fit perfectly into the curve again. I tried putting my helmet on first, and then putting the curtain in, but this just proved to be way too difficult because you can't see what you are doing or where the plastic slits go into the sides of the helmet.I suggest finding a helmet that already has a chin curtain in it. This was pretty much a waste of money.
