The ESS Interchangeable Component Eyeshield (ICE) 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 ICE temple designs, the ICE eyeshield features 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 ICE 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. Rx Lens Inserts available (P-2 Rx Insert compatible with the Profile NVG goggle; Vice Rx Insert compatible with the Advancer V-12 goggle). Authorized for use and issued by the U.S. Army, USMC, and UK MOD. | ICE 2.4 Kit includes Clear, Smoke Gray and Hi-Def Yellow Lenses, an elastic strap, an anti-fog cloth and a protective case. | Note on Size: ICE NARO eyeshields are slightly smaller than regular ICE eyeshields; the temple to temple distance of a regular ICE is ~6 inches while the ICE NARO measures at ~5.5 inches.
