49ers to wear new rivalry uniforms for Week 18 showdown vs. Seahawks

The NFL and Nike's Rivalries initiative celebrates iconic divisional matchups, and 49ers-Seahawks certainly qualifies. The program will run for four seasons, with two divisions receiving Rivalries uniforms each year through 2028.

The 2025 rollout features teams from the AFC East (Buffalo Bills, New England Patriots, New York Jets, and Miami Dolphins) and NFC West (49ers, Seahawks, Arizona Cardinals, and Los Angeles Rams). Each team will reveal its unique Rivalries design before the start of the season.

"The NFL is home to some of the biggest football rivalries and today marks a historical moment for the NFL as we share 'Rivalries' with the world," said Renie Anderson, chief revenue officer at the NFL. "Together with Nike, we are harnessing the power of rivalry matchups to bring fan excitement and community pride to the next level. Through specially designed player uniforms and limited-edition fan gear, we will embark on a journey that inspires competitive spirit and reveals the winner in all of us."

The Nike Rivalries uniforms are expected to feature specially designed player jerseys and limited-edition fan gear, providing supporters with a unique way to express their pride.

"Each participating team will wear a unique Rivalries uniform with designs rooted extensively in local community insights during a single home game against a division rival," the NFL announced via a statement in April. "The designs have been brought to life by pulling inspiration from the history of each market and the aspects of the community that only that team's city embodies."
