Great helmet for the price.
Great helmet so far. I had ordered a small by measurements, but ended up returning for a medium. The small was too small, but hoping the medium doesn't "break in" too much as it would then be a little too large.

Don't hesitate to order this one!

Good bang for the buck.
Very comfortable. Tight around the cheek and mouth area. Light and easy to slip on and off. Some sort of anti-fog would be awesome

Great value for the price
True to size. Fits good and is comfortable. Build quality is better than a carbon helmet I spent twice the money on. I haven't ridden with it yet but I'm impressed so far. The only drawback is that there isn't a tinted visor made for it yet.

Love this helmet.
Great looking helmet that also fits perfect for me. I really like the built in sun glasses. I have had issues with helmets that make it hard to wear my eye glasses, not a problem with this helmet! Ventilation is good also.

Saved my melon!
Came off a CRF-300 at about 70km/h in Vietnam, high sided, broke my collar bone, head hit the asphalt, the helmet kept all the squishy stuff on the inside of my skull. Would recommend!

Great helmet.
Very comfortable and light. Face shield snaps shut easily for higher speeds but will stay partly open in any position I want it to. Sun shade is convenient and works well, though a little stiff. Decently quiet at highway speeds. Comparable to my shoei neotec modular that was wat more money.

Awesome helmet!
I just purchased one of these helmets a few weeks ago for my dual sport and loved it! It lets air pass through the visor really well to reduce drag at speeds and its very quiet. Then the hidden tinted visor is awesome for when you turn a corner and get blasted by the sun. I liked it so much, I just ordered a second one for my wife and I to use them in our side by side. I would recommend this helmet!

Great helmet and great value!
The helmet shipped quick and was just what I was looking for. I consider my head pretty big but the X-large does have a little wiggle room.

How high of a speed can the outer visor withstand?
A shopper on Jan 17, 2019
BEST ANSWER: My son has this helmet and rides a DRZ400. He rides interstate speeds and has not complained about the visor. It is still on solid as I write this.
Can you wear glasses under this helmet?
A shopper on Oct 9, 2018
BEST ANSWER: My son tried wearing some thick framed sunglasses with this helmet and said it gave him a headache. He said the internal visor was better. I understand the arms on most prescription glasses are thin but this information may help someone.
Those who wear glasses, do they fit behind the sun visor?
A shopper on Jan 13, 2020
BEST ANSWER: I have fairly large framed, wrap around style, and they fit with plenty of clearance. The ear pieces are a little tight in the padding, so my glasses are a bit finicky to position, but not uncomfortable.
Do they make tinted shields for these helmets? If so where can they be purchased?
jeremy s on Oct 11, 2017
BEST ANSWER: Unfortunately we do not carry a replacement tinted shield for this helmet.
can I use a cardo packtalk bold with this helmet?
daryl s on Feb 13, 2019
BEST ANSWER: This helmet ran small so I would definitely order a size larger. I like it very well though and would certainly recommend it although I have no idea about the headset use. Haven’t tried it with mine.
Are vents closable?
A shopper on Mar 22, 2018
BEST ANSWER: The vents do not close but the mouth piece closes and opens.
can goggles be worn with the helmet and faceshield?
Mason U on Mar 4, 2018
BEST ANSWER: No that will not work. There is not enough space provided for the goggles.
