But an updated design has more streamlined maple leaf imagery and detailed renderings of the band, its logo, and lead singer Gord Downie from the band's final concert.
The Canadian rockers spent the summer doing a farewell tour across Canada after Downie announced May 24 that he had been diagnosed with terminal brain cancer.
"Everyone knows the story in Canada," Holtby told Sportsnet. "It's one of those things that has turned a positive from a negative. It's pretty amazing kind of what Canadians do. I grew up and I can have vivid memories of listening to my first Hip songs. We even had a class in school, a little part of it that was based on [the song] 'Wheat Kings.' I mean, you just remember it. It's Canadian, it's 'The Hip,' and with me being a huge music lover [it made sense].
"This being the biggest stage for hockey and a lot of Gord's songs have hockey in them, I mean, it ties the two in and I think it'll be very good."
For the band's final show, Aug. 21 in the musician's hometown of Kingston, Ontario, Canada Prime Minister Justin Trudeau was in attendance and 11.7 million people watched the performance on the CBC network live online stream.
Downie's brain cancer fund raised $265,000 by the end of the tour. Holtby said he plans to auction the mask after the World Cup and donate the proceeds to brain cancer research through the band.
