An essential item for every man's closet, this wide-windowpane suit jacket from Ralph by Ralph Lauren features hidden stretch panels that give you plenty of room to move so you can get through your day comfortably. It's an update to a classic style that offers just the right amount of lightweight warmth and texture so you can wear it year-round. Pull out the patterned lining of the chest pocket and you have the sophisticated, dignified look of a pocket square. Pair it with our coordinating suit pants, #B9565 for a complete look. The same jacket is also available in an Executive Cut, #B9562, which is more generously proportioned through the midsection.
