Vulcan Bump Caps have a sporty style, while also being fun to wear. These hard hats are one size fits all with a six panel design that has cpa holes for cooling air flow. Inside, there is a separate, hard plastic Polyethylene shell cap insert that encircles the top, front and sides of your head to keep your head protected against bumps and scrapes. These hard hats are ideal for food and beverage processing, meat packing, warehousing, auto repair, home inspection, various types of mechanical work, meter reading, pest control, and any other environment where blows to the back of the head are not necessarily an issue. This head protection is not intended for use where ANSI certification is required. This style comes in a baseball insert or a traditional hard hat style.
