Q: Can the bbs penetrate the rather large holes in the mask mouth area?
A: Well if they did it wouldn't really matter. I see tons of people that play airsoft with just goggles. Mearsure the holes and seef if they are 6mm wide. If they are I guess maybe 1 out of 500 shots to the mouth piece would get through. If it is 7mm maube 1 out of 150 shots would. 8mm 1 out of 50 shots. But still it doesn't matter. The only really important part our your eyes. I hope this helped and please rate.
