This Seattle Mariners 250th Fourth of July T-Shirt from New Era brings the energy of America's biggest holiday together with the passion of the national pastime in a tee made for the heart of summer. Commemorative screen-printed graphics honor the occasion while lightweight fabric keeps things cool and comfortable. It's the kind of tee that works on the 250th Anniversary of the United States and keeps earning its place in the rotation long after the celebration winds down.
