Ralph Lauren’s plaid workshirt jumper blends utilitarian styling with elevated knitwear, made from extra-fine wool in a double-knit birdseye jacquard for rich texture and warmth. Twill reinforcements on the inside add durability, while Corozo buttons keep the finish classic and refined. A vintage-inspired wash softens the look and feel, making it an easy piece to wear as a layer or on its own.
