  • My fave helmet so far, and I've tried several!
Size: Medium Color: Blue Purple
I'll start off by saying I am not one to spend $$$$ on a helmet. I want one that works, but don't want it to cost more than my mortgage. Trying to find a happy medium of one that is not TOO expensive, but has decent fit and features is easier said than done. I first noticed the look of this one and loved the colors (which the pink and blue are much brighter in person than the stock photos looked). Modulars are usually so heavy, but I liked the idea of having face access when I need it (drink, chapped lips, etc) so this was perfect. The face piece is easy enough to get off and on while still wearing the helmet (though takes a bit of practice to figure out exactly where the slots are without looking). I usually remove the clear visor (though may add that back on for cooler weather riding) and love that the sun visor seats inside the chin piece so no glasses are needed. There is a ton of airflow in the helmet so I even wear it on 90+ degree days without issue. I could even use my microphone on my headset so I can still have coms when riding. The cord on mine plugs in so I just unplug it when removing the chin piece, or set the chin on my shoulder if I'm just taking a quick drink and leave the mic attached. It is more of a round fit helmet so my head shape fits much better in this one than more oblong helmets. I personally don't like how it looks without the chin piece since it is more round and looks more mushroom-y, but I need my com mic anyway so I don't wear it without it. My only "complaint" is that the slide to drop down the sun visor and the slide to disconnect the chin piece are close together and feel similar enough that I have gone to drop down the visor and disconnected one side of the jaw instead. The more I wear it, the less of an issue that is, but did it a few times in the beginning. Thankfully, the jaw stays mostly in the slot so you can just push it back in. ... show more

  • Great Helmet
Size: Large Color: Black
This is a great looking helmet, perfect for summer, or warmer, weather. The face shield and front guard is two pieces that make this helmet excel, however there are some flaws. The front guard is janky at best to put on. Have to come in at an angle and even then it may not lock. Requires force to lock it down. The face shield covers the entirety of your face, not just your eyes. That means any upward wind will get into the helmet. The pros to this helmet are, it is very comfortable. The padding included fits snug and speakers installed are perfect against your ear. This helps with lots of wind noise. Another big pro. With the face guard and the sun visor down, it's dead quiet for the type of helmet this is. That even with tons of venting, and the for mentioned upward wind. You can't go wrong with this helmet. It looks good, has good functionality, and will serve its purpose flawlessly. ... show more

  • Good for the money but for an only helmet
Size: Medium Color: Black
This is a Open faced helmet so don't expect full face protection. That being said it comes with a removable face plate,that gives protection from wind and rain. If you were to hit the face of the helmet with a baseball bat it may give you some more protection than nothing but I'm pretty sure the plate would break off after the first blow, I don't expect that face plate to be there after the first impact and once you start rolling along the asphalt its gonna be a Open face helmet. That being said it's been a nice across town commuter helmet, it's not quiet like a good full face high end helmet but it's not as loud as a AFX dual sport helmet, so it's tolerable. Air flow is fixed, no events to shut off, air flow is pretty good for hot climate here in Florida, I haven't rain tested it yet, I just got it so I can't comment. The way the clear visor attaches looks like a wear point to me and I don't trust it, I'm gonna run dark inner visor as a day helmet only for now. For the price the build quality is pretty good. The packaging was super basic it comes loose in a box inside its helmet bag, no foam packaging just bouncing around loose in a box but it came unharmed. Lenses are clear and distortion free.. great field of vision. Good helmet clasp kinda like off a seat belt . Lining is pretty good. Helmet itself looks very good when worn. Overall a good commuter open faced helmet for 100 bucks that is more like a 140 dollar Helmet, Its a pretty good open face for short money, this can't be your only helmet though, I wouldnt run this 100mph+ or long hauls on the freeway for hours.. a little too noisy and not enough high speed protection. Across town commuting and short hauls only, if you want a real do it all helmet for short money get something like a Icon Alliance or better.. ... show more

  • Awesome Helmet / Price Quality Ratio 10/10
Size: Large Color: Black
Te package finally arrived, the local delivery was messy but boy let me tell you this helmet is amazing!!!! Premium materials, top quality visors as well as the buttons to open and close the internal visor and remove the front mouth cover. Those who have left a bad review about this helmet saying it was built cheaply, you are nuts... yeah probably compared to other top notch expensive helmets this one is not winning but for the price the quality and safety offered are great! The helmet is DOT certified you can feel the great quality just when holding it and when you put it on even more!!! ... show more

  • Cool helmet, bottom piece sucks.
Size: XX-Large Color: Black
The helmet looks very cool. My issue is the chin piece isnt big enough/stick out far enough, if that makes sense. Essentially my chin rubs on the lower face piece and it makes the helmet unbearable. I was really hoping this would work, pretty bummed. The clear visor also fogged up terrible on me.

  • Read this before purchasing this helmet! Your life could depend on it.
Size: XX-Large Color: Black
The plus on this helmet is it looks cool. That's it. The minuses are WAY TOO MANY. I gave this 2 stars then as I typed I had to bring it down to 1 star. The part that covers your face is so flimsy that if you did fall your going to get smashed in the face. The face piece is held in on both sides with plastic mechanisms. It's hard to get in to the socket when the helmet is off. Impossible when the helmet is on. The buttons to release the face piece is right next to the sun shade button.. good luck getting the right one with gloves on and traveling down the road. You'll end up with 1 side of the face piece dangling off till you stop, take your gloves off, remove the helmet, snap it back in, put the helmet back on, then gloves then head on your way... simple. Now that we have discussed functionality lets do comfort. The face piece is directly in front of your nose. if you push on the helmet even slightly you feel the pressure on your nose. There are NO vents at all. It was 80f out side yesterday, first real warm day since I got this. I was sweating all around my head on a 20 min ride from work.. with the clear face shield up! It says DOT approved on the back but I do not trust this helmet at all. you can remove the face piece without hitting any of the buttons, it just pulls off. I have uploaded a video showing everything I have discussed. This does explain why it's a "frequently returned Item" ... show more
