Nitro Aikido Full Face Helmet

I am impressed by this helmet by comparison to my top-of-the-line HJC modular (as sold by Harley-Davidson). First of all everything about this helmet seems more solid -- even the shell (which is Fiber-Glass). I have a big head and concerned about that so I ordered 2XX and once I got my head past the wind dam along the bottom edge of the helmet it was like getting born (in reverse).It felt nice and snug (I have a size 7-3/4 low oblong head. I like the nose cup that directs my exhalation downward to keep the visor from fogging -- my HJC always had a problem with that and I always left the visor opened just a crack. I can do this on this helmet to if I want as the visor has positioning do move it up a cm or so at a time.I like the micrometer adjustment on the chin strap too -- much nicer than the Double DD that most helmets have. Also extra padding between the straps and your neck that double as pull straps you can tug on to get the helmet on.Helmet aced the UK SHARP standard which includes g-Force testing from various angles simulating a high-speed crash. This helmet not only got a 5-Star rating but all head impact points tested in the "green" meaning the amount of g-Force transmitted to the brain would be very low. Most helmets only tested to a 35 mph direct impact so the SHARP standard is way overdue and gives you a much better picture of how your brain would fair in a crash.Sleek and aerodynamic feel to it -- about to try it out on the road today so will report back on road noise and fogging/ventilation too. Seems like a good purchase for a low low price!!

I really like this helmet. I do! It's also the first ever helmet I'm buying.I bought it because of its 5-star safety rating on the SHARP (UK) website as well as it's AMAZINGLY low price! I bought the size S (small) per the sizing chart, and I fully expected it to fit my oval /intermediate oval(?) head. However, it was too small. I could put it on quite alright, but my chin was jutting out under the chin guard.I spent all of 5 minutes trying to convince myself that I could "manage" it.But the voice of my late mother kept ringing in my ears, "Penny wise, Pound foolish!" So it's got to go back!Unfortunately, the U.S.A is quite far from where I live so I'll have to find a buyer for it locally. Sigh.Anyway, I'm placing an order for the size M (Medium) right away!

This is my first helmet. I went into stores looking for a very safe helmet and to determine fit. Once I learned of this through internet research and that it was the cheapest helmet to earn a 5-star rating from SHARP (look it up online if you don't know - great information on impact protection), I bought it.Fit: Excellent. Bought a large and it was perfect for my head. I'm 5'4, medium build, 165 pounds.Road/Wind Noise: Good. The helmet is fairly quiet inside, except for a whistle that has developed over time. I think the vents may have broken into a given position which leads me to the next point...Ventilation: I can't really tell. It haven't been able to notice much of a difference between the open and closed position. I would prefer a little more air when I'm hot, and would love to eliminate the wind whistling sound completely when it's cool outside.Comfort: I have almost 2,000 miles under my belt on it now and I can't complain about comfort. Note that if you like to use earbuds while you ride, this helmet isn't for you. It's snug around the ears (as it should be), and trying to get a bud in your ear before putting it on will only result in the earbud shifting. However if you want a nice helmet with a removable, washable liner and nose guard, it's a great choice.Safety: This is what my choice boiled down to. If all factors were equal, this would be a 4 star review. However given the helmets excellent performance in the SHARP tests, I can't mark this helmet anything less than a 5. If I'm in a high speed accident, I trust it gives me the best chance of returning to my family.

Had some trouble getting the right size. I Ordered an XL that was a little too small. I thought it would be, but the size chart said it should fit. I returned it for a 2XL and got an L in a 2XL box. Just received the new, new, new 2XL.The good news is that the returns were a breeze, and free. I can't blame anyone as fitting a helmet online is, well, just a pain. I tried going to local bike shops in Denver to try one on, but no one carries this helmet.Why all the fuss? This is a ton of helmet for the money. After a recent bike crash I started thinking about my gear a little more and decided I wanted a helmet that was as safe as I could afford. I found out that a DOT sticker means next to nothing. The Snell Memorial foundation has a rating system that I trust, but it is pass/fail. I was hoping for more data. SHARP, in the UK, had what I was looking for, a 5 star rating system, like Amazon! Their website tells you about how they test and rate helmets and gives you a list of manufacturers and helmet models, the cost and how they fared. For example, Arai makes helmets that run from 2 star to 4 star. My quest was to find a 5 star helmet without the Shoei price tag (up to 480 British pounds, $775!) This one filled the bill with a 5 star rating for $119 USD! Remember, models change all the time. Don't trust me, do your homework.For me, a very comfortable helmet. Snug in all the right places, amazingly light. I'm hoping for good hot day performance with good air flow and white finish, but, being in Denver in December, I've got a while to wait for a warm weather!
