Brooks Brothers pocket polo T-Shirt is made with 100% American-grown Supima cotton pique. The extra-long staple cotton showcases richer coloring, softer hand feel and better overall aesthetics. We've added fun varsity stripes to the undercollar and sleeves, which lends a vintage sport vibe to this style. Our signature finish treatment to enhance shape retention and resistance to shrinking, fading and pilling has been applied as well.
