This men's Basic Colorblock Polo shirt from Oakley is constructed with polyester material for a great fit. The Oakley Colorblock Polo uses interlock fabric to handle some stretching and still spring back. There's no seam where the shoulder and contrast-color sleeve meet, giving this a raglan fit for freer movement. A couple stitched highlights on the sleeve and back polish off this athletic design. Oakley optimized their fabric with the triple crown: moisture management, UV shielding and antibacterial technology.
