Good Helmet Padding a little rough, could be more comfortable. The helmet fits well,can see good. For the price,it's a good deal.Shield is easy to take off and replace. Good air flow through vents. Noise from air is tolerable. Over all I like the helmet. April 12, 2016
Nice replacement for HJC FS-15 Trying to find a replacement for a 7 year old FS-15 I got an eye for this helmet. Read about the great ventilation and it did not disappoint. If your looking for a great venting helmet this is it. My only gripe with it is that the helmet strap is about 1/2 inch more to the rear of the helmet compared to the FS-15 so it's a little bit uncomfortable to me but has been getting better as the padding wear in. In general a great helmet at a great price. April 5, 2016
IT SAVED MY HEAD I wore this helmet for about 4 months before I laid down my bike with it! It was comfortable, the air flow could have been a little better. Since this was my first helmet purchase I didn't realize how much I liked it until I wore a different one. BUT when it came down to it and I dropped off my bike it did a amazing job at protecting my head, I fell off and landed on my side and the helmet impacted around my temple. I barely felt the impact and walked away with a slight headache I would buy again! April 4, 2016
solid helmet especially for the price I havent been able to ride with this yet, but i did use this in a car racing event, i left the visor up since it did start to fog, but this was in a car with not much air flow. other than that i really like the helmet and it came with a sick storage bag. easy removal of visor. and i got a separate dark lens which looks sooooo much cooler March 30, 2016
Great helmet! This helmet is much more than I could have asked for from a helmet that's so affordable!! I haven't had to see how the protection is yet thankfully but it feels as though it would do great! It does fog in colder weather when sitting still like most any visor but clears up quickly when you start moving again. Also that can be avoided with the pin lock insert which the visor comes ready for!! Also the design looks even better in person and I have gotten multiple compliments on the look! Great great product!! March 29, 2016
Good helmet at a good price I had an HJC Dirt Bike Helmet that I really liked, so when it came time to get a Street Helmet, I decided to go with an HJC. The gray and purple helmet is beautiful. I chose a size S....the same as my dirt bike helmet. It's a bit more snug than I would like in the cheek area, but fits really well everywhere else, so I am hoping that will break in and loosen up over time. It's not uncomfortable enough to affect my joy or riding or concentration while I am riding. The face shield was REALLY hard to move up and down the first few times that I tried. March 24, 2016
Love this helmet. This is only the 2nd helmet I've owned, first being a Torc Bluetooth helmet. This HJC blows that helmet away! First the fit was a little snug compared to the Torc (both large) not really a bad thing, feels more secure. The material for the padding is much softer than the Torc as wel, huge plus, as well the padding is easily removed but so was the Torc. VENTS, now I know what it's like to actually have them. The Torc had vents but never felt the air, the HJC feels like AC, but again compared to near nothing from the Torc. The weight was no different than the Torc and the shape was about the same, but when riding my head did not seem to bob as much through the air. The one thing I dont like about this helmet is the visor. Maybe I'm used to the Torc which had 5-6? Different notches when opening and they were smooth, also didn't get much fogging until later into the fall season when temps dropped into 40's. So the HJC.. Only has 3 notches, 1 barely cracked to keep your visor from fogging, 2 half open and 3 full open. They aren't like pulling teeth but they do require a little more effort than the Torc, also the 1st notch is easy to miss when opening yet when closing I feel like it ALWAYS winds up on that notch. The fogging... I know it has the new Pinlock visor and maybe when I purchase the visor for that the fogging will go away/ reduce but I was riding on a high 50's day, vents open and the fogging was bad. Maybe I just had really hot breath that day?!?!? Ha. All in all this helmet blows the Torc T10? Out of the water. I love the helmet and if you haven't owned a "nice" helmet and are looking for an upgrade this is it!!! March 22, 2016
Great helmet for the price! This is a great helmet for the price. It is comfortable and breathable and has worked great for me. I do notice that it seems to sit crooked on my head, but that could be my head and not the helmet! March 22, 2016
