The New Era Seattle Mariners 20th Anniversary is the hat New Era is famous for. It is a fitted cap coming in many sizes for a perfect fit. The crown of the hat has what is called a constructed crown. A constructed crown simply means that New Era have reinforced the front panels of the cap for a more rigid feel so the 59FIFTY keeps its shape.

New Era Cap 59Fifty fitted hat for the Seattle Mariners using official team colors, designed with 30th Anniversary side patch and paired with alternate front logo.

With symmetrical look and clean base, this is minimalism at its best.
