Gimmie a sec to shill here.
I got my Christmas gift today, and I'm very happy with it.
Found out about Ebbets Field Flannels from a friend of mine, and they are without a doubt an awesome company. Full reproductions of old defunct minor league team jerseys, alongside Latin American and Japanese jerseys as well.
Everything about this jersey is expertly crafted, no cop-out bullshit. The letters and number on the back is sewn on, not printed, and the entire jersey is made out of a very breathable wool that looks great and period-specific too.
If you are looking for a unique and period authentic baseball jersey, hat, hell even old school hockey and football sweaters, you are hard pressed to find something that comes even close to the quality that Ebbets Field Flannels has. In my mind, it destroys even the best that come out of authentic, MLB jerseys from Majestic.
Their site. They also have a physical store in Seattle, where they make the jerseys on site as well, so it is completely, 100% American made, and it shows.
