The piece is made from a fabric blend of 14.7% wool, 49.8% polyester and 35.5% viscose, with a 280 g/m weight that gives it a substantial, regular thickness for autumn and winter. The wool content brings warmth and a matte, woolen handfeel, while the viscose adds a soft, smooth drape and a gentle fuzziness that feels comfortable against the skin. This combination supports the piece's business-casual, smart-gentleman aesthetic and its standard fit, making it suitable for everyday wear, commuting and travel, as well as for layering as a middle layer in colder weather. The fabric is designed to be machine-washable, which lowers the care threshold compared with traditional pure-wool items, and the three fibers work together to help resist shrinking. The piece features a classic Windsor collar, straight hem, button front and patch pockets with visible topstitching, and it is intended for external wear.
