The New Era Diamond Era 2-Button Jersey in True Navy is the definitive all-purpose colorway for branded team apparel and corporate sports merchandise programs. True Navy is the most versatile color in the professional sports palette, appearing on uniforms across MLB, NFL, NBA, and NCAA programs at every level, and the Diamond Era Jersey in this shade carries that same breadth of application to branded merchandise campaigns.
The deep, rich True Navy finish pairs with virtually any accent color in screen printing and suits the widest range of corporate brand systems. New Era's performance polyester construction underpins this jersey with moisture-wicking properties that manage sweat during active competition and outdoor event conditions.
The two-button placket is the design element that defines this jersey as authentic athletic apparel rather than a standard performance tee -- a detail drawn directly from on-field baseball uniforms that New Era has been producing for professional teams since 1920. Mesh ventilation panels maintain airflow through periods of sustained activity, and the structured side seam construction provides a clean, athletic silhouette.
For screen printing, True Navy is an excellent base that accepts white, gold, red, and orange inks with outstanding contrast and color fidelity. It is the most logo-compatible background color in the Diamond Era lineup, making it the safe choice for organizations with complex multi-color logo art.
SWAGHQ offers custom screen printing on the True Navy Diamond Era Jersey with a minimum order of 12 units. Chest, back, and sleeve placement options are available. The True Navy colorway and New Era heritage combine to produce one of the most broadly applicable branded jerseys in the promotional apparel market.
