I have to point out, I've played airsoft while wearing a fencing mask (For those of yo who don't know, they're made of steel mesh about the same grid size as the average airsoft mesh mask, just thicker. Goggles underneath, of course), and bbs hitting the mask had a nasty tendency to shatter - left me bleeding in several places even under the mask. I don't know about you guys, but I'd rather get hit in the face a couple times than be sliced up by bb shards.
