Glasses fogging up and not being able to see is your worst and dangerous snowmobiling nightmare when trying to keep up with your buddies. This FogEvader is the ticket in any temperature! No fogging at all! This along with a modular helmet is even better because you never have to take your glasses off!! I love it and have encouraged two other buddies into buying them.
I bought this to replace an old one I had from Polaris that worked very well. I expect it to work good, but out of the package it is too small for my large neck to fasten the velcro in the back. I will add some more velcro myself so it will fit me better.
I have one of these from a different manufacturer form years back and it was so great that I bought two of these. They seem to be even better except for one thing. The velcro is sewn to the bottom of the mask and rubs on the back of my neck while riding causeing major discomfort. My old one has the velcro in the middle.
