Gunfire's Airsoft Basics series gives you everything they can share about airsoft masks, given that, errr, they sell eye and face protection to airsoft players... "Masks are gaining more and more popularity in our hobby. Nothing unusual! It is a great alternative to the glasses we are used to. Airsoft masks that protect the entire face, or only part of it, provide a higher level of protection. Does that mean they are less comfortable? Nothing could be more wrong! With the right model for your needs, you may not feel the difference between your glasses and a new mask. Sheet metal will guide you through the world of full face protection and will tell you in accessible words what you should pay attention to when choosing a mask."
