In 1920 the team introduced uniforms containing brown and blue stripes. In the 1930s, thefranchise’s uniform underwent substantial alterations. By 1933 the Bears donned all-orange jerseys with navy numbers and matching black helmets. In 1936, they modified this design into “an early version of psychedelia” by adding three orange stripes to their helmets, changing the color of the jerseys from orange to white, complementing the new white jerseys with fourteen navy and orange alternating stripes on the sleeves, and introducing socks with a similar striped pattern extending from ankle to knee. Because of poor response from the fans and the media, this design lasted only one season.
By 1949, the team was wearing the familiar navy blue shirts with white NFL jerseys, rounded numbers. In 1956, the team added “TV numbers” to the sleeves. The Bears ‘C’ logo first appeared on the helmets in 1962. The logo changed from white to a white-bordered orange logo 11 years later, and has remained unchanged ever since. The Bears added the initials GSH to the left sleeve of their discount NFL jerseys
in 1984 in memory of George Halas.
For decades, the team was known as the only NFL team to wear jersey numbers that were not the traditional block-style numbers (though during the 1971 season, the Bears road jerseys used the block-style numbers). Although a handful of other NFL teams and the Houston Oilers during their early AFL days experimented with rounder jersey numbers, by the mid-1960s the Bears were the only team left to continue wearing rounded jersey numbers. Since the mid-1990s, however, several teams have shifted away from the block numbers in favor of numbers that match a specific team font (e.g. Denver Broncos, Baltimore Ravens, Philadelphia Eagles, etc.) or in the case of the Pittsburgh Steelers, match the jersey number font with the helmet numbers while otherwise leaving the authentic NFL jerseys design alone.
Other variations to the Bears uniforms over the years include the addition of navy blue pants as a part of the road kit in 1984. During the 1994 season, the Bears – with most of the other NFL franchises – introducedthrowback uniforms to be worn in the honor of the NFL’s 75th anniversary. These uniforms with brown and blue stripes resemble the original Bears uniforms worn in the 1920s. On October 7, 2002 the Bears wore navy blue pants with their navy blue home jerseys for the first time, and lost at home to Green Bay before a national Monday Night Football audience. The Bears did not wear the all-blue combination again until the 2006 regular season finale against the Packers, also a loss, on December 31.
On November 13, 2005 and October 29, 2006 (both times in games against the San Francisco 49ers), the Bears introduced an orange alternate home NFL team jerseys. The orange swaps roles with the navy blue on this alternate jersey, as it becomes the dominant color while the navy complements. The orange jerseys were worn again on October 19, 2008 at home against the Minnesota Vikings in a 48–41 victory.
The Bears also wore the orange jerseys against the Detroit Lions on October 28, 2007 and most recently in a November 1, 2009 game vs. the Cleveland Browns (Bears won 30–6). The Bears previously wore orange jerseys as part of a throwback uniform in a Thanksgiving Day game at the Dallas Cowboys in 2004. Their uniforms, especially for their classic look, have been cited as one of the best in the league.
Since 2005, the Bears have worn their alternate orange replica NFL jerseys for one home game a season that is near Halloween. For the 2005–07 and 2010 home openers, the team wore the white jerseys with the navy blue pants. The team is 4–0 in these games, beating the Lions in 2005, 2006, and 2010, and beating the Chiefs in 2007.
The Bears will honor the original Monsters of the Midway during the 2010 season by wearing throwback uniforms of the era for selected games. The uniforms are a nod to the 1940s when the Bears won four NFL titles with Hall of Famers Danny Fortman, Sid Luckman, George McAfee, George Musso, Bronko Nagurski, Joe Stydahar and Clyde “Bulldog” Turner.
