Black Label Three Button Long Sleeve Polo in olive. Introducing our new men's Black Label Pima cotton mouline´ knits. This is a great new addition to our standard men's long sleeve polos. The look is created by twisting two contrasting yarns together resulting in a distinctively modern look. This new fabric is offered in a polo and a tee shirt, both long sleeved. The long-staple Pima yarn has an incredibly soft touch, takes color beautifully and is supremely comfortable and durable.
