True Straight 14oz Onyx Double Black Selvage DenimAn exceptional, textured double black with slub warp yarns. This one is a 13. 5 oz 100% cotton with black sulphur yarn dye in the warp and a black reactive dye in the weft. Translation = these will fade like your indigo selvage except that the fill yarn (horizontal yarn) is black instead of natural. The result will be a killer faded grey with jet black fill. Classic red selvage iD.
