Never change a lens again! The ICE-2X is the world's first combat spectacle kit to feature 2 complete eyeshields in one small hard case. ESS understands that time spent changing lenses is time away from the mission at hand. For this reason, the configuration includes two fully assembled ICE eyeshields (one clear system and one smoke gray system), a hard protective case, an anti-fog cloth, and an elastic retention strap. The ICE-2X is lightweight and "frameless", offering a unique combination of impact resistance, unrestricted views, and interchangeable lenses for excellent eye protection in any light. The high impact lenses offer distortion-free clarity and broad coverage from projectiles. Compatible with all helmets and ideal for weapon sighting. Exceeds MIL-PRF-31013 and ANSI Z87.1 standards. On the APEL (Approved Protective Eyewear List). Mfr's 1 Year Warranty.
