Hat Club partners up again with Seinfeld to spice up their latest set of exclusive baseball cap designs. Here is the Hat Club x Seinfeld 2025 59Fifty Fitted Hat Collection. Only three teams are included in this drop. The New York Mets and the New York Yankees have a cap each, while the Baltimore Orioles has two caps. The front logo embroidery and the Seinfeld logo on the right panel are all embroidered in full color. The undervisor of the bill is in good gray. On the left panel is the New Era Flag, and at the back is the MLB Batterman. Available at the Hat Club webstore.
