I recently attended a two day defensive handgun course at Front Site in Parump Southern Nevada. We were instructed on the proper use of firearms, specifically handguns, to protect our self and our families. When we performed the good guy, bad guy simulator, where you are supposed to take out the bad guys but not the good guys. Man we worked up a sweat!
My safety glasses fogged up when I started sweating so I had to apply C-Clear anti fog gel to stop the fogging. The C-Clear anti fog gel worked wonderfully! It stopped the fogging so I could enjoy the simulations.
I strongly recommend C-Clear anti fog spay and gel!
