The Granite Sturdy Pants are our hard work, made from the highest-end fabrics from Japan and represent our finest craftsmanship. We've patterned these after a vintage pair of A-10 Air Force Pants from World War II from my own personal collection.  Fabrics Main fabric: 18oz 100% Japanese heavyweight cotton twill. Lining: 11oz 100% cotton herringbone. Hardware Talon brass zipper. Vintage-style YKK buttons. Construction & Finishing Topstitching density: 15 stitches per 3 cm ensure maximum strength and long-lasting wear. Reinforced crotch: Double-layer inner construction for added strength. Garment wash: Enzyme and heavy water washed for a soft, broken-in feel. Built by Hand, Layer by Layer: Due to the extreme thickness of the 18oz fabric, any area involving three or more layers must be manually hammered flat before stitching. This crucial step ensures the sewing machine can pass through cleanly and maintain structural integrity. Features 10 pockets with thoughtfully designed storage, including: 4 front cargo pockets with button closures. 2 back flap pockets with secure buttons. 4 additional slip and utility pockets for smaller items. Adjustable button-tab cuffs for a customizable fit at the ankle. Suspender buttons at the waistband for pairing with your own suspenders (suspenders not included). Natural wind-resistant properties.
