This is an official Nike MLB authentic baseball jersey for the New York Mets, featuring player name 'DÍAZ' and number '39' on the back. The jersey is constructed from breathable, performance-oriented fabric with button-front closure, V-neck design, and embroidered team and player lettering in vibrant royal blue with orange trim and white outlining—faithfully replicating the team’s alternate black uniform. Front displays the iconic cursive 'Mets' logo in matching blue-orange-white embroidery, while the left chest bears the white Nike Swoosh and the right sleeve features blue piping detail. Official MLB licensing is confirmed by the MLB logo at the back collar and the Nike/MLB authenticity tag at the bottom hem. The garment includes a hanging retail tag indicating it's new with tags (NWT), likely part of the 2023–2024 season or postseason collection. Designed for fan wear and light activity, it offers comfort through moisture-wicking technology and a tailored athletic fit. Ideal for game days, casual streetwear styling, or sports memorabilia collectors. The black base provides strong contrast for the bold team colors, making it a standout piece in any fan’s wardrobe.
