We already know that the Calgary Flames will be going “full retro” in 2020-21 (and beyond), with the gorgeous 1980s vintage sweaters becoming their full-time home and road jerseys. We already know that the old red home jersey (with black C) will become the third jersey.
But Adidas and the Flames have teased a fourth jersey as part of the long-rumoured “reverse retro” series.

Now, this tease strongly suggests that the Flames will have a black jersey for the first time since Blasty was retired following the 2005-06 season.
