is green under?

Well, Red hats include the Reds (Did not see that one coming), the Red Sox, Indians, Rangers, Angels, Braves, Nationals, Phillies, Cardinals, and D-Backs. Any hat can be green under, its just the way its produced.

not really any. red hats include reds, red sox, diamondbacks, nationals, rangers, cardinals, phillies, and (some) pirates caps.

these teams wear red hats: reds, red sox, diamondbacks, nationals, rangers, cardinals, phillies, and angles. the hats the players currently wear are all black under. but if you want a hat with green under look for old retro hats, a lot of them are green under

no team has a red hat with green under the lid, unless theres a new team called the xmas bombers that we havent heard about

non
they are all black under
