Decent helmet, I can't be doing with goggles so was looking for a good helmet with visor and this has turned out to be perfect for me, the extra sun visor is a fantastic addition.

I highly recommend this helmet. It is super comfortable, has nice air flow on hot days and overall a cool looking helmet. Best bang for the buck. The comfortability was my favorite feature of the helmet.

Great helmet at a really good price. Seems to be well made and is ACU approved.
Good helmet light weight. It could breathe a little better but was not bad
This is an excellent helmet for most all aspects of riding. The only draw back is that it can get hot inside the helmet when riding single track at low speeds during hot days; otherwise it does it all I need it to do. Great helmet for the price.
Ive used this helmet on a few dozen rides so far and have zero real complaints. Amazing value for the money. I also massively appreciate the flip down sun visor.
Nice helmet. Runs small. The inner visor rubbed on my nose. What can I say, I've got a big head.
A M A Z I N G. 120% recommended.
I was looking for a dual sport helmet with a drop down sun visor and a safety rating beyond DOT. This fit that criteria. So why not a 5 star rating? The only vent I can close is on the chin bar and it has little effect one way or the other. The shield does not support pin-loc. No space for internal speakers. The sun visor isn't as dark as I'd prefer.But what else is good about the helmet? The peak doesn't catch the wind. Goggles fit as they should. Helmet fits as expected and is comfortable. Assuming I want ventilation at all times, the ventilation is done well. Peak and shield are easily removable/replaceable. .
