WINDJAMMER 2 "REDUCES WIND NOISE" fits all Full Face Helmets. The original often copied !

My reason for buying this thing was not the wind noise, but that the wind flow inside the helmet bothered my eyes. It eliminates this problem, so the product does its job well in my case. Of course the side effect of this is reduced wind noise as well, but that didn't bother me too much in the first place. (Side note: Have you tried riding with earplugs? - It's quite cool.) Overall, it feels much cosier inside the helmet with the Windjammer on. It's at the higher speeds, over 50-60 Mph, where it's effect can be felt. Thus, I would say it's the most useful on longer distances, on the open road or motorway.The fogging of the visor can be a problem, especially in low temperatures and in town where you need to cruise at low speeds. I have just bought it now, at the end of October, and temperatures have been between 5-10 °C since then. Basically the fogging of the visor was so bad that it seriously impaired comfort and safety. The solution was getting a Pinlock fog free insert for my helmet, which I did, and it resolved the issue. You will still need to open your visor one notch when travelling at or below 30 mph, but above that it's ok. I'm yet to see what it will be like when it's close to 0 °C.Quality-wise it's good. The part that attaches to the helmet is made of an elastic material with sticky gum-like surface on the inside. As you put it on and it tightens on the bottom rim of the helmet, it stays there firmly. The bottom part of the Windjammer, which goes around your neck, is made of some elastic material too. It's more firm and thicker than ordinary cloth fabric, but not too thick or rigid. Note that if you have a large head and use a large helmet, you can find the hole too small when squeezing your head through it. After reshaping it with a scissor, and after a few attempts to fine-tune my technique, I can put my helmet on and take it off again with no trouble.Obviously the tendency for fogging in the cold is a trade-off, but otherwise it's a good buy. Depends what you want, if you want to reduce airflow inside the helmet, it works well.

Takes a bit of time fitting and my helmet has the built in head set controls which you have to cut a small bit out to give access to the control unit!Made a massive difference to wind noise and eliminates the need for ear plugs !Good price and well made !

Most reviews say this is great, some say it doesn't work, so I'll try to give a detailed explanation as to why in my experience I think that is.Well firstly, it depends on your helmet design in the first place. If you have a very well sound-proofed helmet already you might not be able to tell much difference. Especially as this reduces turbulence around the neck area - if you're current helmet is designed to reduce neck turbulence already then the difference with the windjammer might not be so noticeable. Although I've never seen a helmet designed as flush as the result of using a windjammer so there'll probably be minor improvement with any type. On the other hand if you have a helmet that's poorly sound-proofed and has a lot of turbulence around the neck area then you'll notice a huge difference.Secondly, and most pertinently, is that it seems to depend on riding position. I ride a Yamaha Diversion XJ600S, which is a fairly neutral riding position so I can experiment between sitting bold upright and leaning/ducking right forward.SAT BOLT UPRIGHT THE WINDJAMMER MAKES A HUGE DIFFERENCE. In this case the bottom of the helmet with windjammer presents a near perfect parallel to the oncoming wind, which means the wind flows past smoothly and quietly. Compared to without the windjammer where the wind will circulate and eddy round all the nooks and crannies it can find across the irregular surface of the bottom of your helmet causing a lot of turbulence and noise. In this case at motorway speeds, the difference between winjammer on/off sounds like winding all the windows up in a car.In a leant forward racing position however, the top of your helmet hits the oncoming wind, and the bottom of your helmet is now facing slightly backwards. The oncoming wind buffets around the top of your helmet (and ears!) which is quite deafening, the bottom of your helmet is in the wake, it's turbulent around here anyway but not particularly noisy so sealing it off in my experience doesn't make as much difference in this position.So overall if you're riding a cruiser or sports-tourer where you're sat upright (or close) I guess you'll get a lot of benefit, whereas pure sports bikes (eg R6/R1, CBRR, etc) where the seating and handlebar position means you're leant far forward, will notice much less difference (see attached drawing).A couple of final consideration. It can't do much about turbulence from wing mirrors, windshields, fairing, etc. If for example the loudest noise is caused by a badly positioned windscreen then reducing the turbulence around the bottom of your helmet isn't going to be very noticable in comparison.And something that should go without saying - it's a "windjammer" and you don't generate much wind noise at 30mph, so it won't make much difference around town. It's more for country roads and motorway.In summary for what it costs, no matter what you're riding etc, it might be worth trying anyway. Might be barely noticable, but it might be fantastic. I've tried to give a detailed technical breakdown as possible so you can estimate how much of an improvement you're likely to get, but practice will always beat theory so if wind noise is an issue for you then for £12.49 I'd give it a go and see.

Fitted on a Arai helmet and will fit easily to any full face helmet I think, I have a blue tooth fitted to side of helmet, didn't fit correctly but I had taken a chance so managed to fit relatively well, a well made item and very sticky so clings to helmet.I managed to squeeze my head through gap just-very tight and hurt my ears even though I had a balaclava on, after sorting my helmet strap and clothing------- I had a claustrophobia attack and ripped my helmet off my head with great difficulty damaging my nose sheild etc, I never got to road test, so if you have claustrophobia don't touch.But if you don't the product is well made and value for money. The reason for my purchase was to reduce noise as sold for, on my new bike it seems to generate wind noise just at the openning of the underside of my helmet because of deflect of fareing, because I was unable to use, I wore a thick fluffy neck tube which has done the job but in the summer it will be to hot, so very disappointed. Hope this helps.

Easy to fit. Well, that's about it actually. I had to cut the elastic to fit around my Cardo, but still a snug fit. Unfortunately this has made no difference to the wind/road noise between 50 and 70mph, even with ear plugs. New lid next year, so will try for something quieter.

Really good product reduction in wind noise & draft
