HarBearThis is 100% cotton material, 13.5oz, selvedge raw denim, made in USA.
Mott & Bow is partly synthetic material, 11oz (thinner fabric), non-selvedge (lower quality) pre-distressed denim, made in Honduras.
Basically this one emphasizes quality materials and is a more "serious" jean, while M&B emphasizes processing methods and aims to be more stylish. For the price this one is an excellent deal--reviewers agree that this brand is a good example of jeans in the $200+ price range. I would have jumped on this deal instantly if I needed a pair of medium-weight blue jeans.
