Produced in limited quantities each year, 12Milmil12 wool gives the long-sleeve polo shirt its exquisitely soft and weightless finish. The classic ribbed polo collar and cuffs frame the luxury material, while a slim fit creates a sleek, sporty silhouette. The wool of this 12milmil12 garment is obtained from Australian flocks that are specially bred for their superfine fleeces. Measuring just 12 microns in diameter, the exceptionally rare fibres are finer than both vicuña and cashmere.
