MLB and Nike to overhaul player uniforms for 2025 with larger jersey lettering and personalized pants.

Changes are in response to feedback from players, clubs, and equipment managers about fit and appearance.

Nike is addressing issues with color mismatch and sweat discoloration; improved gray uniforms to debut later this season.

The MLB Players Association communicated the upcoming changes to players in a memo.

Uniform adjustments are the result of a collaborative effort between Nike and MLB.
