Nowadays, Mitchell & Ness has license agreements with four of the major sports leagues of the United States (MLB, NBA, NFL, and MLS) to produce and commercialize vintage sports equipment and casual wear.
Some of Mitchell & Ness products include team uniforms (jerseys and shorts) and other casual wear such as t-shirts, tracksuits, jackets, hoodies, hats, knit caps, and other accessories (pennants). The company also has its own brand, "M&N".
In past years, Mitchell & Ness also had license agreements with the NHL and NCAA.
Mitchell & Ness's throwback uniforms were created to reproduce classic to very modern team and player sports jerseys which are either no longer available or hard to find. Mitchell & Ness began producing baseball (Cooperstown Collection) jerseys in 1988, although the company gained popularity in the international retail market ten years after with the introduction of the NBA "Hardwood Classics" line. The company later moved on to reproducing popular throwbacks of American football and NHL players.
Frank P. Mitchell, a former Amateur Athletic Union tennis and wrestling champion, and Charles M. Ness, an avid golfer born in Scotland, together founded "Mitchell & Ness Sporting Goods" in 1904. Their original store made and strung hand-crafted tennis rackets and, using imported woods from Scotland, stolen from England, constructed custom-made golf clubs. In time, they expanded their business, selling uniforms to local baseball and American football teams. When the Philadelphia Eagles entered the young National Football League (NFL) in 1933, Mitchell & Ness supplied the team jerseys and equipment. Mitchell & Ness would continue to outfit the Eagles through the 1963 season.
The first time that the Mitchell & Ness label appeared on a major league baseball uniform, the Philadelphia Athletics, was in 1938. In the early 1940s, Mitchell & Ness began to supply Philadelphia's other major league baseball team, the Phillies. By the end of the decade, the Mitchell & Ness label was appearing on high school and college team uniforms throughout the Philadelphia area.
In the late 1970s, Mitchell & Ness had dropped the team business to concentrate on its retail operation. The store became a leading outlet for field hockey equipment and ski gear. Mitchell & Ness almost went bankrupt in 1983. Owner Peter Capolino told the Detroit Free Press, "By 1983 all the expansion I had done had gone to hell. I fired 100 people, closed two warehouses. I reduced the company to a little store at 13th and Walnut Streets (in Philadelphia). It was down to just me and my wife."
In 1983, a customer walked into the store and asked if Mitchell & Ness could repair his 1960 Pittsburgh Pirates game-worn vest, and his 1949 St. Louis Browns game-worn shirt. They were both made of wool flannel as all baseball uniforms had been during that era. Mitchell & Ness found that it could do it, and with the realization that Mitchell & Ness was capable of this task, an idea was born: Reproduce historically accurate wool-flannel baseball uniforms. Mitchell & Ness recruited history buffs and sports gurus most notably Capolino's friend Bob Downes. They dug through old newspapers, periodicals, books, programs, and old film footage. They consulted vintage uniform collectors throughout the country and visited the archives at the Baseball Hall of Fame in Cooperstown, New York.
Major League Baseball (MLB) teams had stopped wearing wool flannel jerseys by 1972 to wear double-knit polyester jerseys. In a dusty warehouse in North Philadelphia, Mitchell & Ness discovered rolls of old baseball flannel from 50 years earlier. They were still carefully wrapped, untouched, and in like-new condition ready to be cut and sewn. The flannel was sewn. The lettering and patches were recreated and applied. The jerseys were completed, and they were offered for sale. The first shirts sold almost overnight. So did the second batch of a dozen or more. In time, Mitchell & Ness attracted customers from across the United States. Sports Illustrated wrote a flattering piece about Mitchell & Ness in June 1987. The New York Times wrote about the company two years later.
In 1999, Mitchell & Ness expanded into the history of the National Basketball Association (NBA), when it introduced its Hardwood Classics collection of basketball jerseys. Football followed a year later with the Mitchell & Ness Throwback Collection. In 2002, the National Hockey League (NHL) granted Mitchell & Ness rights to remake vintage hockey sweaters.
Mitchell & Ness now has on file every MLB uniform worn since the founding of the original Cincinnati Red Stockings in 1869.
In 2007, Adidas purchased Mitchell & Ness in order to get into the retro-apparel style market. On May 29, 2008, the Philadelphia Phillies announced that they had signed Mitchell & Ness as a naming-rights partner of its clothes store at the Phillies' Citizens Bank Park. The Mitchell & Ness Alley Store is in Ashburn Alley beyond left-center field.
On January 24, 2011, the Reading Phillies, AA affiliate of the Phillies announced that they had signed Mitchell & Ness as a naming-rights partner of its apparel store at the R-Phils' FirstEnergy Stadium. On March 23, 2012, Jonathan Yuska was brought on as Head of Mitchell and Ness. In May 2016, Adidas sold Mitchell & Ness to "Juggernaut Capital Partners", a Washington, D.C. based private equity firm.
Owner Peter Capolino reported to Sports Illustrated that Mitchell & Ness had annual sales revenue of $1.5 million per-year in 1998. Revenues rose to $2.2 million in 1999[14] and were $2.8 million in 2000. Sales were more than $5 million in 2001 according to ESPN.com while Capolino reported annual sales of $4.5 million in 2001 to USA Today. Sales rose to $23 million in 2002.
