We've taken our Sport-Wick moisture-wicking technology and crafted a flat tricot micropique for a smoother, tighter fabric. Not just a sharp look - it's snag resistant, too. 3.8 ounce, 100% polyester tricot. Double-needle stitching throughout. Tag Free. Taped neck and side vents. Flat knit collar and 3-button placket with dyed-to-match rubber buttons. Set-in, open hem sleeves.
