so, I was thinking of picking these up in place of the Lancer Tactical goggles for my cousin, as a goggle, and then get him a lower mesh as well. Has anybody heard or used these? If so, are they actually that safe? Something about that gap concerns me. http://www.airsoftgi.com/mobile/product_info.php?cPath=548_542_543&products_id=11178 Thanks!
