The story
The brand was introduced in 1955 by Munsingwear, a Minneapolis-based underwear and military garment manufacturer, when it launched the Original Penguin golf shirt in the United States. Munsingwear was for many years famous for its union suits, an undergarment consisting of an undershirt and underdrawers combined in a single garment. The company was also said to be the originator of the classic golf shirt. In 1996, the brand was bought by Perry Ellis International after Munsingwear filed for bankruptcy in 1991.
