This vest is constructed of 13-ounce flame-resistant INDURA® Ultra Soft® duck (a blend of 88% cotton and 12% high tenacity nylon). The lining is 10-ounce flame-resistant Moda-Quilt® (that's Modacrylic batting quilted to INDURA® Ultra Soft® twill-face cloth).

There are two large front pockets as well as two inside patch pockets with fire-resistant hook-and-loop closures. The coat also features a low-slung back 'kidney' flap and a rib-knit collar made of flame-resistant Nomex®. And like everything Carhartt makes, this vest has been job-tested. Guaranteed.
