Biggie or Bigfoot played by Christopher Heyerdahl is one of Sanctuary's most beloved characters. Although, he is an intimidating looking bigfoot like creature, he is intelligent, compassionate and one of Helen Magnus's dearest friends. This cotton sporty style shirt helps create his signature style. It doesn't have any branding or tags so it may have been custom made by production, but I am not 100% sure. It can be seen on screen in Season 4, Homecoming. Obtained privately from Legends Memorablia who purchased almost all of the props and costumes from the production.
