Mariners x One Piece 2026 Stripe Jersey – Exclusive Collaboration Jersey, Celebrating the Pirate Journey and Mariners Baseball
Mariners x One Piece 2026 Stripe Jersey is a special collaboration product between the Seattle Mariners and the legendary manga/anime series One Piece, released in 2026 to celebrate 30 years of Luffy’s journey and the Straw Hat Pirates. This collection is designed specifically for the 2026 season, when the Mariners enter their 50th year since joining the American League (1977–2026), while also aligning with a major milestone for One Piece – a story that continues to conquer the world.
