Inspired by the same Diamond Era textured fabric as iconic baseball caps, this New Era Men's Diamond Era Full Button Jersey is designed for on-field performance, but is also perfect for fans. This moisture-wicking, snag-resistant jersey is made of 5.3-ounce, 100% polyester Diamond Era jacquard. It features raglan sleeves, underarm gussets, shirt tail hem, and engraved New Era dyed-to-match buttons and more for comfort, durability and style.
