Helmet is snug at first. Like uncomfortably snug. I’m a few months in at this point and it fits absolutely perfectly, do not order a size up. It’s relatively light for the price and the built in visors are great, plus they still allow you to rock goggles if you fancy. The helmet looks cool and I have been a crash dummy, and I’m still alive so that’s a plus. Took a spill at about 20mph on a woods trail. Head hit super hard on dirt and rocks and I walked away with cracked ribs and a very mild concussion so I’d say she work's. Plus the helmet came out in one piece without even cracking the visor. Definitely worth the purchase. Would buy again.

Both me and my son wear this helmet when we ride our GX3 scooter that goes 40 mph. It’s comfortable, quiet, functional, and versatile. My son crashed going about 30 mph and the helmet held up very well. I pulled the helmet apart to inspect and make sure there was no serious defects after the crash that would need it to be replaced. All I found was just a few scrapes on the side of the helmet and visor where he made contact with the pavement. I typically wear a size large helmet, but decided to go with a XL because I have 9 piercings, 2 of which are 00g and 1 is an industrial so I need the extra space to comfortably slide my head in and out without irritating my ears. I also wear AirPod pros and the larger size accommodates nicely to keep them in place. Visors and padding are super easy to remove in order to thoroughly clean when needed.

I don’t have anything bad to say about this helmet. I read some other reviews about sizing. Just make sure that you buy one size bigger than what you normally wear. I followed that advice and the helmet fits great. The helmet fits snug without feeling like the padding is scrunching your face. The helmet is super light weight and it has a sleek design just like the pictures. I saw some reviews where the built in tinted shades were difficult to function. They were not, the slider that brings them over your eyes works great and provides great protection from the sun. Best helmet I’ve ever owned for this value.

Me: I wear glasses, size XL, head size 61cm on the dot, head shape: intermediate oval,modestly toward round but definitely not halfway toward round. Initial, out-of-the-box: It weighed 1606g on my digital scale. Initial fit seems dead-on accurate (mild chipmunk cheeks, mildly tight, not painful but a little annoying--they break in). All liners completely removable. No audio system cut-outs (I'll figure it out). The one thing that absolutely annoys me is that this helmet only has a D-ring chin strap. Come on, you can add a buckle strap for $2 but now I have to go out on retail and spend $10-$15. This obsession with hitting an MSRP of "$159.99" vs "$162.99" has to end. It's like they know this is going to occur. The padding around the chin strap isn't sewn to the strap so that you can adjust it for the buckle that you will eventually buy. I purchased it because it can be converted to a snowmobile helmet with a few part change-outs (breather box, double-lens anti-fog visor). Those parts are from another brand that sells the same helmet for snowmobiling, see "Castle X Mode Dual Sport SV". First ride: Neither visor used, nose vent open. I was just getting a feel for fit & comfort. It was a maintained forest road in Colorado that eventually turned into an unmaintained road with huge fallen trees that you had to divert around in technical slow tight off-the-road both-feet-on-ground over-smaller-fallen-trees try-not-to-stall heavy-breathing off-the-bike-and-get-it-over terrain. Total 3hrs out and back. It's a comfortable helmet for me. I never once though "this thing is uncomfortable." It will fog up you glasses though on the very slow stuff without either visor. It has a horizontal elastic chin cloth that blocks air from coming up from below so all of your breath goes upward. Colorado is a low-humidity place. I'm torn on cutting that out because that is useful in other scenarios. We'll see. My glasses were a little tight and I had to bend them back into shape because I pulled them off my face a little wrong. I never really thought the tightness of the glasses were a real problem though. They didn't hurt and I didn't notice them except for getting the helmet on and off. Second ride: I'm done with this helmet only because I wear glasses. Colorado is low humidity. It was sort of trying to rain this day. I stopped to adjust something. I couldn't see anything within 10 seconds because my glasses fogged up. This is super annoying. I'm going to find a modular helmet (chin moves up) so I can deal with the glasses fogging up. Seems like a nice comfortable helmet. The visors look like they have good non-distortion. I wish it worked because it fits great and parts are available. I didn't ride at any high speed and used neither built-in visor so go find another review for that. I'd keep the thing if it it didn't make me blind if I come to a stop (or slow crawl).

Excellent helmet, fit was snug at first yet, needed after some period of break in, it fits great. After regular use it is fitting better. Same with sunshine shield ; as the more I used it the easier it became to bring it down. The helmet keeps the noisey wind out and can hear my music on my ear phones off my IPhone, I get a lot of compliments on the look of the helmet, and I think it is starting a trend; more bikers are wearing these type helmets. It’s tuff, dropped it a few times, minor scratches. Tinted visor after a few uses able to bring it down easy. Clear shield comes in handy on the freeway. Only draw back is the triangle removable chin plate always come loose yet a little black duct tape has solved that issue.

I bought this and have ridden with it a few thousand miles now. I hate it. Its got a TON of wind noise, to the point I need to put my head below my windscreen to hear my engine at all on a DR650 with a stock exhaust. the sun visor is almost useless, you can't adjust it low enough to actually do more than the top lip of the helmet anyway so its just a wind catcher to wear out your neck. there is zero room for any sort of headphones in this thing, so don't plan on listening to anything but the deafening wind. With that said, I do like the flip down sunglasses. the front vent can be opened and closed as well which is nice. Overall, its a motocross helmet trying to be an adventure helmet, and still has all the problems a motocross helmet has for adventure riding.
