The first time we played it was about 60 degrees and raining earlier that day so the humidity was very high. It fogged up so bad there was no way I could ever see my opponents in the woods. They claim it will never fog? Yeah right. Plus there was a sharp edge on the part that goes over your ears so my ear was cut and bleeding after the first game. My friends with JT masks had no fogging problems whatsoever. This mask sucks for the price you pay. Get a JT thermal.
