Ninth Inning is a lifestyle clothing company from Texas. In their about section they describe themselves as a group trying to "create a product that portrays the significance of baseball & celebrates the American classic as it should be." I really dig the aesthetic of their vintage branding which is something they strive for as well.
One of the items they sell is a black Ebbet's Field flannel hat. I'm a big fan of 9, but personally, I could do without the DODC ("Do Or Die Crew?") on the side of the hat.
Below are some the t-shirts in their Summer Series line.
