It is rare to find new designs in personal protective equipment (PPE). Trousers may have new pockets or padding. Helmets may have additional ventilation. Goggles have improved anti-fog holes. But rarely is PPE combined.
EyeMuffs have combined hearing protection and safety glasses in a single unit that does not rely on a connection across the top of the head. This removes the common conflict and discomfort between earmuffs and safety glasses or goggles.
