This 14.15 oz. dry denim greatness bears the resemblance of an old, '50s style, denim. True to history it is constructed of ring-spun warp and weft yarns with irregular thickness, as was often the case back in the day on workwear fabrics. Also true to its heritage is the dark, but not blackish, indigo warp that is dyed in pure indigo. With wear and wash, the yarns will interact, and you'll reap the rewards that heavier ring-spun denim produces — evident slubs, a pleasing crosshatch as well as a marbling -effect. It's the irregular yarns in both warp and weft that render the crosshatch effect, and the built-in tension formed by the yarns that produce the marble effect after washing. As this denim is dyed in pure indigo, it will age to a clean, blue redcast tone. The greatest part of these jeans is not what they look like new, but rather the complete opposite - how they will look tomorrow, and the many days to come. Enjoy ageing, it is worth the trouble.
