Seasonal Rewards:

Seasonal Rewards are cosmetic items or titles granted in Rocket League for completing the competitive season’s reward requirements. They serve as a record of a player’s participation and rank progress during that season, and are usually distributed after the season ends.

These rewards are used as status cosmetics rather than gameplay items, so they do not affect car handling or match performance. In Rocket League, the term most often refers to the exclusive items tied to Competitive play each season.
