The exterior of the Archer Herringbone Vest is a classic and rich herringbone texture blended with wool and polyester. The interior is filled with DuPont™ Sorona which is a renewably sourced plant-based insulation that is naturally soft and fluffy but contains supreme warmth retention. At the interior collar band, you’ll find an 18 wale corduroy lining that keeps your neck comfortable and warm but also adds style points to an already impressive piece. A durable YKK metal zipper seals in the warmth and is finished off with a premium branded leather zipper pull.
