  • Update: Think of it as more of a quality 3/4 helmet than Modular.
Size: X-Large Color: Black
Update: I was a little harsh in my initial review as I was disappointed with the chin guard part of this helmet. I have since wore it a few times as just a 3/4 and I have to say, it’s a great 3/4 helmet! If you’re looking for an affordable 3/4, this is a legitimate option. The face guard should be considered a side bonus. It’s not easy to put on, helmet should be off when putting that on. Then I like to sip water when I ride, this doesn’t lift, so I need a straw lol. So opt for the ILM version if you want a true modular with a tuck away face shield. PROS: Helmet looks great, the included visors work well and the outside clear cover does a great job of blocking the wind. CONS: because of the sunglass toggle switch, you can’t put a Bluetooth device in the usual side location. I had to put it almost in the back of my head, lol, the mic barely reaches. I recommend the ILM version if you’re looking for an affordable Modular to 3/4 face convertible helmet, the one where you can put the chin guard part all the up and behind to the back in a locking position, so it’s out of the way and you can alternate easily between a 3/4 and full face. ... show more

  • Beats a $$$ Harley Helmet
Bought my first bike this year, a Harley - went for style over function and bought a half helm from the Harley store to go with it. $300 later, the chin strap attachment I had to get (I sucked at the ring-tying) sucks hard - I'm getting bugs lodged in my ears (I ride a lot in country fields), and I'm clinically deaf from the wind after a short 45-minute ride. Sizing Chart: The sizing chart is pretty accurate, I have a big head (lot of hot air in there I guess) and where I thought going a size up was going to be roomy it's actually quite snug but still comfortable. Chin Strap: Kicks the crap out of both the default ring on the Harley helmet as well as the additional clip I had to buy. You "un-snap" your chin strap similar to Ski boots...just lift and pull. Where the Harley Helmet moves a bunch when I'm over 50 mph, this helm stays put. Padding: Extremely comfortable - the snug fit makes it kinda tricky putting my glasses on after I put the helmet on, with an upside that the padding holds my glasses in place so there's no "nose sliding" as I look around. The padding is a little bit tight on my ears - but this helps for a more quiet ride. Visors: Clear visor is indeed super easy to remove. Tinted visor is a snug fit when down, very little if any air coming in under the visor. My only complaint here is that the sun glare can make visuals opaque - this is the only reason I gave it a 4 and not a 5 on comfort. Bear in mind - this is sun in the face at 6:00pm, midday it's good. Chin Guard: TONS of air flow coming in through the chin guard - literally feel the air moving to the back and around my head. At a price of $70 - you seriously can't go wrong with this helm. Love the design too - went with the green one, wouldn't go back. ... 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

  • Can’t beat this helmet for the look and Price!
Size: Medium Color: Black
This helmet met my expectations. The helmet is lightweight and comfortable, I love the features it has. Being able to remove the padding to clean and also offers the options to add Bluetooth. The visor being removable is like having 3 different styles of helmets. Being DOT certified is a big plus since it’s your safety net! Showed my buddies they want to make a purchase of this helmet after seeing it in person! Thank you! Ride safe! ... 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.
