Growl Towels are the Grizzlies' trademark gold rally towels given to fans at every home playoff game. Originally white, they made their debut in 2004 in the third and fourth games of the franchise's first ever playoff series. They switched to gold when the Grizzlies changed their team colors for the 2004–2005 season. Since 2013, Growl Towels have rotated various popular team slogans such as "Grit & Grind", "All Heart", or "Ain't No Runnin' in the M", and each towel identifies the playoff year, round and game number it was released. They became notable across the league during Memphis' seven consecutive playoff runs starting in 2011. During their 2013 run to the Western Conference Finals, the Grizzlies printed over 100,000 towels.
