OTG (Over The Glasses) Interchangeable Lenses Goggle System ensures ballistic eye protection with 2mm thick polycarbonate lenses that meet ANSI-Z87-1 and military standards for impact protection (MIL-DTL-43511D). The tactical OTG goggles will fit over your glasses with 7/8” temple cutouts on each side and extra space beneath the lenses, so you can wear protective eyewear without sacrificing your vision. Made with top and bottom vents to prevent fogging and anti-scratch technology, the removable lenses will retain your field of vision while at the range or in the field (comes with smoke, clear, and yellow lenses). In addition to ballistic protection, the military safety goggles offer UV 400 protection against harmful sunrays. For a comfortable fit and feel, the ANSI approved goggles come with a thick 3/8” foam padding that rests on your face while wearing. The adjustable strap features a rubber grip and moveable hinges on each side to prevent the goggles from pulling away from your face while worn over a helmet. Included in the ballistic OTG goggle system are a cleaning cloth, goggle cover, and a hook and loop carry pouch to protect your goggles when not in use – attach the pouch to a variety of gear, including MOLLE compatible items.
