Thank you very much for viewing. This is a New Era x Cooperstown cap. The size is 7 1/2 (59.6cm). I purchased it at Second Street, a recycle shop. The color is a blue-gray, and the material is wool. I liked the design and material and bought it, but I haven't worn it much because the size didn't fit. Please purchase it with the understanding that it is a home-stored item.
