MATERIAL100% polyester Mitchell & Ness In 1904, Frank Mitchell and Charles Ness met up in Philadelphia to establish Mitchell & Ness Sporting Goods. At first, they specialized in stringing tennis racquets, constructing custom-made golf clubs and making uniforms for local Philly baseball and football teams. In 1933, the Mitchell & Ness label made their NFL debut when they started making uniforms for the Philadelphia Eagles, a partnership that would continue for 30 years. Their success continued in this field till 1985, when Mitchell & Ness received a request that helped them pivot in a new direction. A customer inquired about making repairs to his game-worn 1960 Pittsburgh Pirates vest and his game-worn 1949 St. Louis Browns jersey. This sparked an idea that would change everything. Today, Mitchell & Ness Nostalgia Co. offers authentic vintage jerseys and apparel collections for the MLB, NFL, NBA, NCAA and MLS. M&N NBA Chicago Bulls Heavyweight Satin Jacket ''Red''
