Sporty, lightweight design eliminates the bulkiness and weight of a goggle. Dual pane lens provides the ultimate anti-fog performance by isolating the temperature difference inside & outside of this eyewear. The outside and inside of the lens is coated with H2X™ Anti-fog Technology for even more resistance to fogging, due to extreme temperatures. The thermal system provides anti-fog protection in the worst weather conditions or extreme-temperature working environments. Vented foam carriage provides maximum dust protection, as well as a sufficient airflow outlet for heat. An outer polycarbonate lens protects against the environment, while an inner acetate lens is designed to prevent fogging.
