It protects you from going blind and getting shot in the face
Weaknesses:
Fogs like crazy scratches easily hard to clean and hard to breath
Review:
Well i bought this in a 98 custom package and so i went to go test out my gun that week end. the mask started to fog and i couldn't breath very well. the masked was so fogged that i walked to a another person not on my team and he shot me in the neck.
I got shot in my masked and i could clean it very well.
Conclusion:
Don't buy this gun. Unless You cant afford something better
