Jacket from Frizmworks. Herringbone Wool Hunting Jacket is a reinterpretation of a vintage-inspired hunting jacket and the British RAF MK3 jacket. The model has a relaxed fit and is crafted from a wool and nylon blend with a classic herringbone weave. The jacket is lined with plain-weave cotton and features an antique gold YKK metal zipper. The garment is left untreated after production to preserve the natural texture and character of the fabric.
