Was looking for a light colored unit, this was on sale, O'Neal has always been a good brand name, I was reluctant to order online, the sizing chart worked great..helmet fits perfect.

This is my first dual sport helmet, so hopefully the visor will not kink my neck...can always remove.

I like the built in shades, saves from torture of sunglasses and easily moved when needed.

Exceeded my expectations for the price...good quality feel.

I give it 5 stars because......
this helmet is terrific based on price. this is not a $900 Shoei helmet, but for such a low price the Oneal is an excellent choice. I got the white. It's a matte white not glossy. The helmet is surprisingly light weight which is always a plus. It comes with a removable chin piece for those chilly days. The oval shape fits my head well and is comfortable. Perfect for the casual rider.
