Affordable and reliable
I bought a small size . It fits really snug .it's comfortable, has a drop down sunglasses; but if it's very sunny outside, they provide minimal protection for your eyes. I can however use regular sunglasses under the clear shield to protect my face. And it has vents for warmer weather

Excellent Helmet
This helmet is fantastic value for money. Identical to my old name brand helmet at a fraction of the price. Beautiful inside and out and the fit is fantastic. My old helmet was getting loose so I took a chance on this one and I have not been disappointed. Arrived very well packaged with a lovely helmet protective pouch. I would not hesitate to recommend this helmet. I noticed some negative reviews on this helmet regarding fit. Ensure that you measure your head or have someone do that for you to get a good fit. Wind noise - no more than my old helmet - about the same. Weight - no more than my old helmet. This is in my opinion a good 3/4 helmet for a very fair price.

Very nice helmet
This is well built, nice style and look to it. Flip down dark sun visor is fantastic. Clear face shield is sturdy. Adjustable vents work well, open, you can feel the air pass through it inside of the helmet. Comfort is good I did have to go up from large to XL. Much better. They run a bit small. Overall great hemel I would buy again

Nice helmet at a great price
Very happy with this helmet. I wear an XL in a full face, but I went with the 2xl. Perfect fit, glad I stepped up a size. Has slots for speaker system.

Good value
This helmet arrived in the wrong color but that was ok as I planned to paint it anyway. The flip down sun visor is DARK which is a very good thing and has functioned flawlessly the hundreds of times I have used it. The face shield is ok with a slight warp around the edges but that's just how theses things are. The chin strap buckle is a great convenience and works well. I ordered the XXL which fits like a L/XL I definitely recommend going one size up from what you would wear with the big brands. I have somewhere around one hundred rides on this helmet and it still looks new as I keep it in the bag. Overall I would call this a good helmet for the money and would highly recommend this helmet for someone getting into the sport. If your a helmet snob this is not for you as there are a couple of got spots that show up after a few hours.

Size
The helmet speaker slots are not even on your ears. The helmet fit really tight and I went a size bigger than normal. Not a good choice.
