Big Bill has been outfitting the toughest crews across North America for decades. From drilling sites to refinery decks, we build flame-resistant clothing engineered to stand up to flash fire risks, brutal weather, long shifts and demanding industrial wash cycles. This industry shaped us, and today our FR line remains one of the most trusted choices for oil and gas workers who need protection they can count on. When it comes to shielding you from thermal hazards, we have you covered head to toe. Our FR coveralls are built for mobility with designs that allow crews to bend, climb and work freely hour after hour. If your day demands storage, our coveralls and work shirts offer an array of pockets to keep tools and essentials close at hand. Need high-visibility? Our Canadian market garments meet strict CSA Z96 standards, helping crews stay seen and stay safe on active sites. And for harsh conditions, we offer insulated and waterproof FR options made to take on wind, rain and cold without compromising compliance. Because oil and gas work is hard on gear, we engineer fabrics and constructions that hold up to industrial washing and daily wear. Durable, reliable and purpose-built for real-world conditions, our FR clothing helps crews stay protected, comfortable and focused on the job.Every Big Bill FR garment is arc rated and compliant with NFPA 70E, ASTM F1506 and CSA Z462 standards so you can work with confidence, shift after shift. Layer with our FR base layers for added comfort and protection.
