Nudie Jeans - Mens Gritty Jackson JeansThis 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 produce ?
