Hard Hat is engineered to help provide extended comfort, head protection, balance and stability. The lightweight design features a replaceable brow pad and unique design to the top of the hat with a short brim for better upward visibility. A four-point ratchet suspension system with height adjustment delivers the balance and stability you need in demanding work environments. Accessory slots accommodate 3Ms cap-mounted earmuffs, headgear, face shields and welding helmets (all sold separately). Hard hat meets the requirements of ANSI/ISEA Z89.1-2009 Type I, Class C, G and E.
