if you have glasses there could be a fogging problem, just have to open/spread  it a little, i work for the local telecom. in a bucket truck in Rochester NY.(enough said) i love this mask and you can pull down and still have a hat and a turtleneck(muffler) so to speak i love it. when the high is 16 I'm  very happy with this and like all things wind will eat through it but it will cut it down...for the money you can not beat it
