The MLB collection features a two-tone design and the Cooperstown logo. The silhouette is the 59FIFTY, a representative style of New Era. A unique core is built inside the front panel to create a classic silhouette that resists deformation. Available in sizes with approximately 1cm increments, without size adjustment. You can wear it in the perfect size, from those with small heads to those with large heads. Also, since there is no adjuster, the rear silhouette is beautiful, and the shape of the head looks clean.
