These Goggles are Very durable. Pretty funny how i found out, I voluntered to get shot by my friends tippmann with flatline barrel, to test its accuracy. He shot me a couple of times, and then we started to go inside. I tripped over a couple of pieces of plywood left over from their new fence. I landed on the goggles, with my shoulder, with all of my body weight. I thought i had cracked the lens, but i didnt even leave a scratch! Over all these are good strong goggles.
