Hamilton Carhartt created his first pair of bibs for Detroit railroad workers of the 1800s. Everything, from the pocket placement to the thickness of fabric, was formed by the insights of workers who relied on our gear to get the job done. These men's overalls are designed with all the durability of our original bibs plus the added insight of more than 100 years. Built to last, they're made of heavyweight denim that only gets better with time.
