Carhartt Mens Relaxed Fit Denim Carpenter Jean. Toughness in the form of 15 ounce, 100 percent cotton denim. This thick but soft fabric is made with all-natural cotton fibers that are breathable, machine-washable and made for rugged wear.

Made to sit just below your natural waist, these men``s jeans provide a comfortable fit every time.
