The number one requested feature on hard hats, as determined by surveys of wearers, are cooling vents. This hard hat is the first in North America to successfully integrate cooling vents in the top of a hard hat while maintaining the impact protection required by ANSI Z89.1-2003. The Vented Hard Hat from MSA Safety Works features a special rain gutter to help channel rain from going down your neck.
Interesting Facts; Hard Hats are tested to provide a wearer protection from a force roughly equivalent to a 16 oz. hammer dropping 40 feet.
