There is no salary cap in MLB. There is however, a luxury tax system which makes it more expensive for a team to carry a high payroll. How it works is that there is a threshold ($189M in 2015); if a team's payroll is above that limit, a tax of 17.5% of the amount they're over by is paid to the league as a fine.
By 1954, New Era, which has been making caps for 85 years and has a 70-year relationship with MLB, was producing a uniform hat for each baseball team, and today, the company provides about 2,000 per team a season. For fans, hats come in hundreds of styles, including plaid, argyle and camouflage.
