Perfect for summer travels, casual outings, and the office, the men’s MERINO PATTERN 150 POLO shirt delivers breathable, odor-resistant performance. This dress up-or-down polo is made of Smartwool’s signature merino weave with Core Spun tech. Core Spun means merino fibers are wrapped around a durable nylon core, increasing this shirt’s strength. A relaxed 3-button placket gives off casual vibes you can button-up for style. Offset shoulder and side seams help eliminate chafing under backpack straps.
