The goggle system shall be comprised of a high-temperature, flame- and impact-resistant goggle lens and frame, a flame- resistant, elastic goggle strap, and a goggle retention system.

This retention system will lock the goggle onto the helmet at the back brim, which will prevent loss of the goggle when it is stowed or in the donned position. Both inner and outer surfaces of the goggle lens will have an antiscratch and anti-fog coating. Both ends of the lens will be reinforced with a fiberglass-insulating label for extra durability at elevated temperatures. The lens will be low profile, optically correct with a nominal thickness of 1/16". The goggle strap will require a one-time adjustment, which facilitates donning while wearing gloves.

The inner edges of both lenses are designed to connect when the lenses are flipped down. The lenses are fastened to a single key and cable (spring ) system that allows the two (2) lenses to move simultaneously. The entire assembly is mounted to a brass plate, which is fastened to the center of the front brim of the helmet shell.

RETRO-REFLECTIVE TRIM
