Great Helmet But ! This helmet is not great for speed over 150MPH Helmet vibrates violently at high speeds, Now that I sold my yamaha R1 And Own A KTM 950 SMR it works great for me now. March 24, 2014
Great helmet I haven't worn this helmet riding yet, so I can't comment on air flow. The quality is really good for the price. The interior padding is very soft and comfortable. This graphic looks even better in person, especially with a smoke shield. The shield comes off very easily. It's a little more difficult to put back on, but nothing to complain about.

Very nice The amount of features you get for a helmet that's sub $300 is amazing. Light weight, good airflow, super soft removable padding and pretty quite. Not to mention it's overall looks. Great helmet. October 28, 2013
Fantastic Helmet! I bought this to use when I took the MSF course so I wouldn't need to wear a junked helmet that potentially hundreds of people sweated in. Glad I did! This helmet fits very nice, it was a little weird at first but I think it was just because I'd never worn a full-face before. Now that I have a bike and use the helmet more I can say that I really do like it. The biggest surprise by far for me was the weight. It's VERY light. If it weren't so obvious in other ways that I was wearing it, I'd probably forget I had it on. It looks great too. I really recommend this product. Mine is flat black with the Iridium Mirror shield and it looks awesome. December 10, 2013
Light weight, Stylish and Usefull features First of all, i would like to point out the AMAZING fast shipping and customer support i got from revzilla, i live outside the US and i contacted revzilla via phone and they helped me with every question i had about this item and i recieved it about 5 days from shipping so thats pretty amazing. Now about the helmet itself. when i got my first look at it when i unboxed it i knew i did the right choice. very cool style, wide visor (recommend to buy the Iridium visor) good venting points and switch open/close looks very durable. i took this helmet for a first run, good air flow, low noise level though i expected it to be more quiet and wide view. overall i was realy enjoying the ride with this helmet. just one problem i seem to notice my lips/mouth can touch the chin/mouth part of the helmet which was kinda wierd. one more thing about this helmet, chaning the visors is ridiculously easy, very good job on that. overall pros- super-lightweight helmet great view amazing style good airflow changing visors super easy cons Fits kinda wierd for me mouth/lips can touch the chin part of the helmet i expected it to be more quiet but its okay September 7, 2013
Great Commuter Motorcycle Helmet This is my first helmet so take my review with a grain of salt but, I'm very happy with this helmet so far. The helmet is lightweight, good airflow, quiet even at 30+ minute highway rides of around 120 km/hr. The materials on the inside of the helmet are quality and very comfortable. I have no idea how the helmet would hold up in a crash thank G-d, but the helmet feels incredibly solid despite it's light weight and it's crash test rating is reassuring. All in all if you're looking for something basic, yet quality at a reasonable price, this is a great helmet. September 20, 2013
Great Helmet This is the first helmet I've owned, but have ridden around using friends helmets so I don't have much to compare it to. My initial thoughts are it is a great entry level helmet. It is a lot lighter and more comfortable than the other ones I have used, $80-$120 unknown brands. The noise level is really low. Few short 30 minute highway rides and the wind didn't affect me. It does fog up a little bit in cold morning but cracking the shield a bit takes it away. I have a solid black and in stop and go traffic in the south I never felt my head getting hot. Overall it is a great helmet for anyone looking to get their first helmet and don't want to spend to much or get a below standard quality. The only reason I'm giving 4 stars is because I don't have much to compare it to and it is leagues about anything else I shortly used. September 1, 2013
A little help with sizing I watched more videos and read more reviews than I could count before buying this helmet. As others have stated, the padding is a little thin at the forehead but it does not bother me. To be honest I love this helmet. It feels light, breathes well, is high speed friendly and who couldn't be happy with the looks?My big issue when looking at helmets on line was the sizing. My head measured at the high end of AGVs medium range. I decided to get a Large knowing that I might need to buy thicker inserts, but that isn't the case. August 2, 2013

Tobe F: Not sure how to answer this question but my head is more long than round. This helmet fits great. My only complaint with it is that the face guard seems to be awfully close to my mouth. If I were to get in an accident and land on my face instead of the side or back, I feel like it could potentially break my jaw. Otherwise, this helmet is awesome.

Hope this helps.
