This version of the 634s jean has been overdyed black with a fugitive pigment dye which is an unstable and un-permanent dye that fades to later show the indigo denim underneath. Essentially this is a denim that begins black and fades to indigo in high friction areas, or what the Japanese call the "atari" fade. The cut on the 634S is a golden one, it's not too slim and not too relaxed, that perfect in between for a flattering look from top to bottom with a perfect sized leg opened for stacking or cuffing. These jeans are made of sanforized denim that has been overdyed, these will not shrink at all once washed due to the overdye process which gets rid of all the shrinking that may take place.
