Similar to the 2X but for a more narrow fit.

Never change a lens again. The new ESS ICE-2X NARO™ is the world's first spectacle kit to feature two complete eyeshields. Designed specifically for smaller faces, this new configuration eliminates time spent changing lenses, allowing users to quickly switch between pre-assembled eyeshields to adapt to changing light environments. Additionally, this new configuration helps extend product life by eliminating wear and tear on lenses that can occur when swapping lens colors. Authorized for use in the USMC & USAF.

As with all products in the ESS Interchangeable Component Eyeshield (ICE™) Series, the ICE-2X NARO™ 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, ICE NARO™ 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.
