Polish Pride at the Plate — 2025 Mariners Polish Heritage Night Shirt Giveaway
When T-Mobile Park lights up for Polish Heritage Night on July 31, fans won’t just witness a divisional showdown—they’ll take home a story stitched in red and white. The 2025 Mariners Polish Heritage Night Shirt Giveaway is an official element of the club’s themed-ticket program, a tradition that routinely packs the ballpark and raised thousands for local cultural groups last summer.

Front and center, “POLSKA” arches across the chest in a vivid folkloric pattern inspired by Łowicz cut-paper art, while the Mariners’ trident-shaped “S” replaces the letter “S,” fusing Northwest baseball heritage with centuries-old craftsmanship. On the left sleeve, an outline of Poland shaded like the national flag reminds wearers of home—whether that’s Warsaw, Gdańsk, or the vibrant Emerald City.
Polish-American roots run deep in Seattle; immigrant shipbuilders helped shape the waterfront, and modern entrepreneurs keep Pierogi Fest buzzing in nearby Capitol Hill. This shirt nods to that legacy and, with every themed ticket, routes $5 to the Seattle Polish Foundation to fund language classes, folk-dance troupes, and community outreach. Demand speaks for itself—last year’s allotment sold out within hours, and social feeds lit up with photos of fans draped in red-and-white during the seventh-inning stretch.
Limited to the first wave of purchasers, this keepsake will never return to retail shelves. Secure your ticket, claim the tee at the gate, and join thousands of voices chanting “Let’s go Mariners!” in two languages. Wear it on game day, at the annual Polish Festival, or anytime you want to spark a conversation about heritage, hardball, and the unifying power of sport.
