The Softbank Hawks unveiled special 80th anniversary uniforms they plan to wear when they host Legend Days during the season (at least once a month).
The uniforms are based on designs used in 1938: white with navy lines. The cap features a logo based on the Hawks symbol used in 1947. The lettering on the front chest is based on what is used on present-day uniforms. The double lines on the sleeves are also the same thickness as on present-day uniforms.
