I use this when snowmobiling and also when I am snowblowing the driveway. It is very comfortable and keeps my head very warm. My hat size is 7 3/4 this mask fits just perfect. I don't know how it would work with any smaller or larger head/neck.

When wearing a helmet it can make the helmet more snug, also th helmet may pull the head piece over the eyes. What I did to combat this is to put the mask into the helmet first then pull it all on over. Sounds complicated but its really not once you have tried it.

I give it a 4 star because the seam around nose ripped a little about the 4th time I used it. Once I sewed it up it has lasted quite well.

Thanks for reading my review!
