Once upon a time, when sports teams in North America cut their own deals with individual uniform manufacturers, you had your (largely) national players such as Russell Athletic, Wilson, Champion Athletic, to name a few.
But some teams went for more smaller, more regional uniform manufacturers. Let's remember some of them.
W.A. Goodman and Sons/AIS: Both were Los Angeles-based (AIS is still in business, though). The former supplied uniforms to most of the L.A. based teams (Dodgers, Kings, UCLA football), but both also supplied uniforms for the New York Mets (Goodman for the World Series Champion 1986 Mets, and AIS for the Mets in the late 1990s; they were also behind the "Mets in Black" thing used from 1998-2011; a backstory behind that can be found here: http://www.espn.com/espn/page2/story/_/page/lukas%2F110512_new_york_mets_black_uniforms/sportCat/mlb)
Southland Athletic: Based out of Terrell, Texas (a 45-some minute drive east of Dallas), they were the original suppliers to the Dallas Cowboys; and they were the ones that came up with that unique block number font the team used for their first 20 years of existence.
Gerry Cosby: Based in the New York City area. I've seen their tags on Giants, Knicks and Rangers jerseys.
Are there any other of these so called "regional" uniform companies you remember? Post them here.
