Levi's - Close your eyes. Think 'jeans.' Now open. They were 501s, right? Theyre literally the blueprint for every pair of jeans in existence burned into the worlds collective cortex ever since Levi Strauss (the man himself!) invented them in 1873. To this day they theyve never gone out of style. And they never will. Crafted in 14.25 ounce denim.
