I had the N87 and enjoyed it but upgraded to the modular N100.5 6 months ago. Have done 20k km in it and love it. The thicker cheek padding, the vastly improved chin wind deflector and especially the draw string neck roll which keeps both the cold and the wind noise out.. without earplugs it’s quiet unless you are riding with the visor up at around 90-100km/h where it has a slight whistle sound. I choose to ride with Alpine Motosafe ear plugs almost all of the time. They allow all the important sounds in and just cut the dB irritating sounds. The Nolan N-Com System transferred easily over from the N87 (made by Sena I believe) and it’s low profile controller tucks into a removable blanking panel so there it doesn’t stick out awkwardly like so many others I see. The helmet itself has been super comfortable on multi day (3-4 days) of 500-600km/day rides and the ability to easily open the chin guard/face and flip up with one hand on the go allows fresh air to flow.... I’m sure the Shoei Neotec II is also a great helmet and perhaps the pinnacle for many riders, however at 40%-50% more expensive, the Nolan reaffirms itself as outstanding on all measures.
