Fits great
I bought this helmet when it was on sale and I am very happy with it. It is as good quality and looks as expensive helmets from the store. I am very happy with it.

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.

Full Review
since i haven't seen a full review for this helmet i'll write it up since i took kind of a risk buying it without much to go off of. i'll give a few basics since they provide very little info followed by a more detailed review. Appearance: looks pretty good (some tend to look bulky or too round in person) shape: intermediate oval to round shape noise: a little louder than average (to be expected with an open-face helmet) padding: pretty thin features: flip down sun visor and quick-release chin strap are nice size: smaller than normal (bought XXL)(i wear an HJC i10 XL and this fit almost right would probably fit perfectly if it was more of an intermediate oval shape) Its good for the price but if you want a better helmet i'd probably pay the extra for a better helmet. i primarily bought this for lower speeds while instructing so i wasn't as concerned with getting the most protection i could. the padding is very thin so if you're concerned about the concussion aspect of a head impact i'd suggesting looking for an ECE rated helmet. coming from an HJC i10 helmet that fits perfectly, this pinches just a tiny bit on the front and back of the helmet and leaves a tiny gap on the sides, if you have a round shaped head this should fit well. overall i'd recommend it to someone who was some extra features associated with more expensive helmets but are on a budget but if you want full protection i'd spring for a better name brand helmet and going into an actual store to get something that fits just right.

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

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

False labeling !
