Authorized for use in the USMC & USAF. The ICE-2TM US Unite Issue Configuration includes: One fully-assembled ICETM eyeshields with Clear lenses. 1 set extra Smoke Gray lenses, an elastic retention strap, an anti-fog cloth and a protective hard case. As with all products in the ESS Interchangeable Component Eyeshield (ICETM) Series, the ICE-2TM is a lightweight, frameless eye protection system that offers a unique combination of high-impact resistance, unrestricted field of view, and interchangeable lenses for effective eye protection in any light condition. Equipped with the new ICETM temple designs, ICETM eyeshields feature improved fit with headborne equipment and increased ease of temple adjustment and lens interchange. Adjustable earbends allow for a comfortable, secure, anatomical fit. Telescoping temples offer bend-to-fit inner-wire ear tabs and a snap-on leash system. All ICETM lenses provide 100% UVA/UVB protection, and exceed ANSI Z87.1-2003+ and the U.S Military .15 caliber ballistic impact test MIL-PRF-31013. Note: ICETM lenses are still interchangeable, making it possible to integrate additional lens colors or replaced damaged lenses.
