Review on Ultimate Protection: Empire Paintball Helix Thermal Lens Goggle - Unmatched Quality and Performance! by Kevin Carr

They are inexpensive, have a thermal imaging lens and fit well. The bottom of the mask is a bit short, leaving the sides of the face slightly exposed, but time will tell how it all works. I sweated a lot, dripped into the mask, A LOT, and it didn't fog up once. I played all day in the sun in 80 degree weather and it was pretty hot in the mask but overall it was as clear as it gets. I photographed the head, had to wipe it off, but again it was clear with no haze. The best return on your money.
