These jeans are constructed of 14.5-ounce flame-resistant denim (88% cotton and 12% high-tenacity nylon). They’ve been pre-washed to provide a soft, comfortable feel, and have a relaxed seat and thigh to give you plenty of comfort. The brass zipper fly features protective Nomex zipper tape and the high-tension snap closure at the waist is arc resistant. You’ll have no problem fitting the 17-inch leg openings over work boots. For fire-resistant protection in high-quality jeans that are built to last, this is a great workwear choice. Imported. Inseam: 30-36 even. Waist sizes: 30-36, 38-54 even. Color: Denim.
