A face protector for protecting a worker's eyes and face comprises an auto-darkening filter unit which in turn comprises a filter pane or ADF pane and an electronics unit driving the ADF pane, the electronics unit being configured to switch the ADF pane automatically from a transparent state to a darkened state. A hard shell unit comprises a shell carrying an ADF unit with the ADF and being shaped to protect a wearer's face, the shell being manufactured of a plastic material. A soft shell unit comprises a cap for protecting the crown of the wearer's head and a neck protector for protecting the wearer's neck, the soft shell unit being made of a combination of flexible fabric with support elements.
