WINDJAMMER 2 "REDUCES WIND NOISE" fits all Full Face Helmets. The original often copied ! (P&P 99p Worldwide) by Proline

I bought this in 2014, and just took it off the helmet now in 2016 (yeah, I know, used that same helmet for waaay too long). In any case, it lasted the distance. And it helped a lot in decreasing wind noise. Totally worth the price.

18-Month UpdateStill have the same Windjammer 2 on my helmet although I am beginning to see signs of slight fraying in the material around the material edge at the jaw (perhaps stubble a few days after each shaves is beginning to get to it?). Can't even remember what a loud ride with wind noise was like, except that I recall my ears would hurt for some time.Original PostSo I received and after the super easy task of putting this this my helmet, trying it on, then loosening it a bit so its not pulled so taught (which pulls it away from the neck) I thought to myself... 'its 8pm and a little below 32 degrees but I just have to find out well this thing cuts down on noise'. So, after donning my cold weather riding suit I head for the interstate, but not before a ride around town. The ride over though I have to say "This thing is WONDERFUL!"This thing really works! While it will keep you warmer in cool weather (a pro), the con of actually being hotter in the summer is a reasonable cost considering the very real hearing damage which will surely be done without it. While it isn't a replacement for ear plugs at extreme speed (75mph) I would feel confident going without earplugs for extended periods of time when driving anywhere from 0-74mph.Real Data: As an human and environmental health graduate student I am well aware of the value of hearing protection. Were you to ride your motorcycle for a living, federal OSHA permissible exposure limits (PEL) limits 8hr exposure sound limit to 90db and only 2hr @ 100db (average). Unfortunately, these regulations are a careful mix of employee health statistical expectations and employer cost feasibility and The National Institute for Occupational Safety and Health (NIOSH) "found that significant noise-induced hearing loss occurs at the exposure levels equivalent to the OSHA PEL." NIOSH published recommended exposure levels without concern of employer costs for adequate employee protection (feasibility) based solely on health risk data. NIOSH limits are: 8hr @ 85db and 15min @ 100db.In a 2004 study by the Charted Institude of Environmental Health (UK), it was noted that all tested helmets (open face plus visor open and closed both with/without neck seal) within the study generated greater than 85db at speeds lower than 30mph (50kph). Interestingly, the data also suggest that neck seals increase the allowable speed prior to exceeding the 100db recommended limit from 65mph to more than 75+mph (the db/speed graph [fig 1.0] didn't quite go high enough to make a definitive (~77mph?) observation).Using this AND earplugs?... would probably make my ears ring from the resultant deafening sound of utter silence, lol.Food for thought... if you get this thing only then to turn around and blast music from your MP3 players directly into your ear I fail to see how your actually reducing your risk for hearing damage... Luckily, this thing makes wind-noise quite enough that don't have to do so, so turn the volume down a little.Drive safe!

This is very well made and has some amazingly sticky stuff on it that really works. Further, you can pull it back off and it continues to stick over and over, making it easy to adjust the fit. It also doesn't seem to leave much in the way of sticky residue.It does, indeed, improve the seal along the bottom of my helmet and keeps my head more comfortable on colder days, although it also gets hot when the weather is warmer. In 80 degree temperature, it became almost unbearable in there, and I had to remove the product and store it on an old helmet until next winter.The big issue, however, is that this doesn't solve the problem I was trying to address: Wind noise. I didn't use sophisticated sound measuring equipment to evaluate the change, but if my helmet became quieter, it certainly wasn't by enough to make much difference. More importantly, it did not eliminate, or even reduce, my need to wear earplugs whenever I ride. That's what I was hoping for.This is a good product for anyone wishing to increase his or her comfort when riding in cold weather, because it really does reduce drafts. As far as noise reduction is concerned, however, don't expect much.

I haven't gotten a chance to ride with it yet, but I am disappointed that they didn't include a stitched hole for the helmet mounted audio systems that quite a few people have. I cut a hole in mine and then put another piece of velcro over the legs and pulled the cover up to it. Hopefully it'll hold and not be a hot spot for wind noise.It doesn't seem to take give any extra coverage other than in the chin area, but I'm not really sure where all my wind noise was coming from. Hopefully this will cut a lot of it down.Update - this thing DOES cut down quite a bit of wind noise, but on my LS2 assault it's just not enough. The reduction in noise is nice, but I'm going to have to keep wearing my earplugs.
