ESS 740-0501: Battle tested in the most demanding theaters, the ESS Profile NVG is the only authorized goggle issued by the U.S. Marine Corps. It is also issued by the U.S. Army, the U.S. Air Force, many NATO governments. ESS\' flagship goggle, the patented Profile NVG is a compact military/tactical goggle system with no compromises. Created with direction from elite U.S. Special Forces groups, and more widely used than any other military/tactical in the world, it has all the advantages of a low-profile, night-vision-compatible frame without sacrifices in dust filtration, field of view, impact protection, or anti-fog performance. The extra-thick, 2.8mm polycarbonate lenses offer maximum impact protection and 100% UVA/UVBfiltration. ESS\' advanced ClearZone FlowCoat lens treatments provide the optimal combination of anti-scratch coatings on the outside of the lenses and anti-fog coatings on the inside. The Profile NVG has a full-perimeter ventilation and filtration system that minimizes lens fogging and filters airborne particles, dust, and splashes.
