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.

This helmet is very versatile. It comes with a full face cover that is removable if you want to. It comes with a double visor as well, one outer clear one and a tinted inner one. It eliminates the need for sunglasses. It doesn't feel too heavy and can easily turn your head to check lanes before merging. It looks great with its flat matte black finish. One of the cool things to me was that when I initially saw it, It reminded me of one of the Star Wars Empire Tie-fighter helmets. It's similar in shape. And then on the side of the visors it has what looks very much like the Empire's Cog symbol.

Works flawlessly, way better than I expected.

I love the overall look of the helmet. Very jet fighter looking and it still kept a slim profile without compromising protection. I have a Nolan modular helmet that is great, but darn it makes me look like a bobble head with its size.

Pros:
- Overall look
- Ratcheting chin strap (some say not as "safe" as the standard chin strap btw)
- Removable outer shield and face guard both w/ quick release
- Inner tinted visor
- Removable liner
- Deep well circular comms cutout for more recessed addition
- Fit runs a little larger than expected (not by much, but enough that you may want to go w/ a smaller size)

Cons:
- If you were to remove the face shield, you'll need to have a backpack or side bags to store it
- Outer shield (depending on manufacturer defect) can pop out if/when riding w/ it in the up position
- Zero instructions (it would be nice to know how to do or use certain features for some of the 'not-so-obvious' features)
- Inner shield slider switch is directly in a location where you could put a bluetooth comms unit
- (Update) I had only taken side roads w/ this helmet, but once I hit the highway, there's a loud whistling sound when you have the inner visor down and outer shield up, with it down it's fairly quiet. Anything over 40mph will need the shield down if you want quiet.

I needed a new cool and cold weather helmet going into the season and wanted to give this style a try. In FL, winters consist of cool (sometimes cold) mornings and warmer afternoons. A full helmet works for the winter mornings but is sometimes too stuffy for the afternoon. I liked that I could use the facemask in the morning and easily remove it for the afternoon. There are no vents in the helmet, so I would not recommend using the full shield above 85 degrees. It would be too hot.
This helmet is very aerodynamic and is the first one I have had in a long while that does not lift up when I get to highway speeds. I do ride behind a windshield. First time out I stood up at about 45 and the helmet was very comfortable in the windstream. The full shield is optically correct, and it is easy to forget it is even there, until you go to scratch your nose and bop yourself in the face.
So for the bad: I took away 1 star for 2 reasons. The first is that the chin strap is too far back and presses on my throat. It would be nice if it could be shifted slightly forward. Second is that the full shield is very difficult to push up with 1 hand. It snaps down onto the lower part of the helmet shell and is designed to be raised with 2 hands. I have tried to raise it 3 times at low speed and twice one side popped off in my hand. Both times I had to pull it off completely and tuck it under one leg to pull over, take the helmet off, and pop it back on. Very dangerous when that happens in traffic. Sometimes you have to raise it while riding, so I would recommend wearing the helmet and practicing raising it with one hand. It can be done; you just have to be careful. It has to be rotated upward while pushing in at the top. Any force applied outward will pop it out.
EDIT: After riding a few weeks (daily) here are my updates:
1- the chin strap attachment points loosened up after a day or two and now it sits comfortably on my neck as it is supposed to, so that problem is resolved
2- the full-face shield now pops off most times I go to lower or raise it, whether I use 2 hands or not. The attachment points seem to have loosened up. It fogs up under 15mph because it is so close to my nose and mouth, so I used to use 1 hand to drop it down once I got to the main road, Now I have to put it down before riding or leave it up for the whole trip. The shield must be raised to put the helmet on and then lowered, so this morning I had to take the helmet off, reattach the shield, and put the helmet back on 4 times before I was able to successfully lower the shield and start riding. The shield is such a PIA that I have clear safety glasses that I use in the evening and just leave it up, since it is a little warmer (the internal visor is smoke, so i can't use it after dark). I will probably just toss the shield and use the facemask during colder mornings.
I want to remove another star, but I do like this helmet. It is very comfortable, cool looking, and the removable facemask is nice. It's just that the full shield is so poorly designed, like an afterthought. If there was a clear option for the internal shield, I could toss the full shield, use sunglasses during the day and it would be the perfect helmet. For that reason, I will leave it at 4 starts and still recommend the helmet.
