Notre Dame's Shamrock Series jerseys are a testament to the program's rich history and tradition. The latest iteration, unveiled on July 8, 2026, will be worn in the season opener against Wisconsin at Lambeau Field on September 6. This year's design pays homage to the pioneers and the Acme Packers' blue and gold roots, while also incorporating the fire of the Fighting Irish. The jerseys bear a striking resemblance to the ones worn in 2024, which were a tribute to the 'Four Horsemen' and their historic victory over Army. The Shamrock Series, which debuted in 2009, has become a tradition, with Notre Dame currently holding an impressive 12-0 record. The series has seen the Irish face off against various opponents, including Washington State, Army, Maryland, Miami, Arizona State, Purdue, Boston College, and Syracuse. The program's apparel partner, Under Armour, has provided unique jersey and helmet combinations for these games, adding to the excitement and tradition of the Shamrock Series. The series has become a significant part of Notre Dame's football identity, blending tradition with a modern twist, and it continues to captivate fans and create memorable moments in college football history.
