The Chiba Lotte Marines unveiled their 2018 Marine Festa uniforms during a press conference earlier today. The uniforms were modeled by Yasuda Hisanori and Yudai Fujioka.
Wave patterns were used as a base design element to represent the hope for Tadahito Iguchi to create and ride a “Marine Wave” in his first year as manager. The seagulls are a symbol of the Marines.
The Marines logo on the chest is based on the arched Lotte logo design used by the Lotte Orions in 1969.
