Love the features on this helmet. I had to take out the cheek pads, they were too tight. Without them the helmet fits good. I bo ught it so I could ride in cold weather. I usually wear a half helmet. Great price. I received it in about a week. Thanks Leatherup.

This is a great helmet for the price. I've had it for three weeks and the is only one minor complaint. The visor scratched when a bat( a flying bat) hit me while riding. The people at the Leatherup were so nice to send me a replacement visor. So far I've found the helmet to be fairly quiet, the vents work pretty well at highway speed. I had a $300 helmet before and this one compares almost 1-1 to that one.

Good fitting helmet., love the the shaded flip down visor......but tried it on a long ride and the vent clips on the face guard right above the red release button, flew off..... Wasn't worth the money sending it back just for the front vent loss.. Frank Chino CA.

I brought one previously that I was extremely happy with. This time finish was dull and it would not lock in position. The customer service I received was inadequate when it came to the return of the product.

I purchased this helmet about 2 years ago. It fits perfect after some wear. I ride most of the time with the visor up and have had no problems. The smoke inner lense fit over my sunglasses when there is really bright sun during my early am ride to work. Its too dark in regular sunlight to wear with darker sunglasses. The lower chin assembly is removable, and not too difficult to put back on (I am not a mechanical guy). Make sure the screws on the side are tight, but not too tight. Mine loosened up on me and I had to pull off the side of the road and fix it. I am very pleased with this helmt, it fits really well on my head. I am comfortable in it. I have worn it on 25 degree days and 104 degree days, the vents are easily opened and closed based on how much air you need circulating. There is very good airflow through the helmet on hot days. I would recomend this helmet to others. Over a Million Satisfied Customers Since 1998.
