The BOSS Slim Fit Passenger Polo Shirt in Open Grey is a sharp, slim-cut polo for smart-casual wear. Stretch-cotton piqué with a little elastane keeps it comfortable and helps it hold its shape. Details are kept minimal: a flat-knit collar with no stand, a two-button placket, flat-knit cuffs on the short sleeves and a tonal woven BOSS logo patch on the left chest. Wear it under a jacket or on its own.
