These are tactical goggles from Swans. The light smoke lenses provide good visibility in outdoor airsoft games, from sunny to cloudy conditions, and the vents kept them completely fog-free, making for a comfortable game. The thick lenses provide a great sense of security. I've used them three times in airsoft games. Upon close inspection, there's a small scratch on the lower left part of the lens, but it's not in the line of sight when worn, so I don't think it's a problem. Thank you for looking.
