MLB and New Era go for some fine details for their latest collaboration. Choose from all 30 Major League Baseball teams with the MLB Sunlight Pop 59Fifty Fitted Hat Collection. The fabric for the dome and uppervisor takes on the customary on-field hat team color, while the undervisor is made of grey fabric. The 3D front embroidery features the team logo. Embroidered across the panels of the dome are UV-activated patches. Wear this under the sun and you’ll see the patches change colors. The New Era Flag appears in white on the left panel, while the MLB Batterman at the back is in a tri-color embroidery. View the whole collection here.
