I love my Nolan N104 and was fortunate enough to have a frost/fog insert lens included with my helmet purchase. For those of you that don’t and have a pinlock shield on your brand of helmet, you can purchase your frost/fog insert lens separately, for around $30bucks. They work well and will actually keep your helmet from fogging up in the rain or frosting over in cold weather. Of course the easiest way to keep this from happening is to stay home enjoying a hot toddy around the fireplace. 😉
I thought this was a handy video for the proper installation!
