Rolando Romero seems to be planning on having one of the best performances of his career later Saturday against Manuel Jaimes ... 'cause TMZ Sports has learned the boxer's copped all kinds of cool custom gear for the battle.
We're told Romero (a.k.a. Rolly) was hooked up with some Bruce Lee and Kobe Bryant swag from his go-to guy Aztek Kustoms ... just ahead of his 10-round tilt with Jaimes (16-1) at T-Mobile Arena in Las Vegas.
