I have been playing paintball for a long time, my first marker was a PGP pistol. I have used many different types of goggles, and I must say I am very disappointed with this product. It fogs terribly. The lens are easy to remove and the unit cleans up nicely. But the fog issue is without question the worst possbile thing that can happen when wearing goggles.
I would not recommend buying this product due to the inability to prevent fogging.
