Carpenter jeans are a type of denim pants designed for functionality, originally intended for carpenters and construction workers. They feature extra pockets and loops—especially a hammer loop on the leg—to carry tools and keep hands free while working. Typically made from denim or canvas, these jeans are looser around the leg to accommodate the tools and provide comfort. They often have reinforced stitching, extra rivets, wider belt loops for heavier tool belts, and sometimes built-in knee pads. Though created for utility in work environments, carpenter jeans have become a fashion trend, known for their relaxed fit and distinctive utility style. They provide a blend of practicality and comfort beyond traditional jeans, often made with softer denim and inside fleece linings for added warmth.
