Great helmet with lots of features. The vents work well and I especially like the dual visor. I raise the face shield in town and lower the sunvisor. I recommend it to anyone.

I order a medium and found the weight to be close to 6 pounds. The manufacturer clearly states that it is not to be worn in the open postion. I found with it all the way back you feel the pull from the weight on the back of your head and you would still need good gasses or goggles because the wind come under the tinted visor and into your eyes. My head measured 22 1/2 and the medium was a perfect fit. The locking device is plastic and I am not sure how that would hold up when needed or how long it would last if you wear the helmet all the time. The air flow through the vents is really good. I did get a whistle sound when I tilted my head down but that and the wind noise was not too bad. Overall I would recommend this helmet. For the price I don't think you can beat it!

This helmet fits nicely. The sun-visor is very easy (even for a new rider) to use and handy especially in a setting Florida sun. I am very satisfied with my purchase. I priced a similar helmet at the Harley store for $250.

Love it! Now I don't have to carry 2 helmets around, no matter what the weather I'm prepared. the flip back face cover doesn't add any extra weight or catches wind.

A really terrific helmet for the money. Lots of great features and a comfortable, secure fit. It is sweet looking and after just doing a 1000 mile trip with it I can say it passed all tests with flying colors. My only complaint would be the clarity of the tinted visor. It is a bit distorted. That being said, all else is super nice. Leather Up is a great company with products that reflect excellent value. I have always been happy with my purchases.

Great value! I was worried about what kind if helmet I would be getting for the price. I am very impressed. It is well built and very quiet. A huge improvement. The visor and all moving parts move smoothly and feel solid.
