This bib overall isn't just protective against electric arcs and flash fires, it also has durable 10-ounce Moda-Quilt® lining to keep out the cold. Made of rugged, 13-ounce, 100% cotton duck, it features a high back with FR elastic suspenders and high-temp nylon center-release buckles. The chap-style double front was designed for durability and increased thermal performance. The zip-to-mid-thigh brass zippers have Nomex® zipper tape, a protective flap and an arc-resistant snap closure. We also placed Nomex® zipper tape along the brass zipper fly. There are FR melamine waist buttons, and weÆve included a hammer loop as well as multiple tool and utility pockets.
