This is a customer color hard hat available exclusively from Texas America Safety Company. The Skullgard Jumbo cap style hard hats with Fas-Trac III ratchet suspension are designed to protect your head from heat. This hat fits head size 7 to a size 8.5. They are ideal for work environments that contain high heat but can be used for many other environments. The major difference between these products and our other hard hats is the material. Since these hard hats are made of fiberglass, they can withstand temperatures that standard plastic cannot. The strips of fiberglass material are what give these hats the great thermal protection that they enjoy. Skullgard fiberglass hard hats are top products for individuals who work in the welding, building construction and ship building industries. These particular helmets come with a ratchet suspension, so you can make quick adjustments and get an optimal fit. The Skullgard hard hats also meet the ANSI requirements for Type I helmets as outlined in ANSI Z89.1 2014,Class G electrical-low voltage)
