The 59Fifty baseball cap from New Era. Official Major League baseball cap as worn by the professionals on the field of play. High-profile, 100% wool cap. Raised 3-D logo on front. Embroidered MLB logo on cap's reverse. Made in U.S.A. Getting the right size of fitted baseball cap is pretty simple. Carefully measure your head with a tape measure - about a half-inch above your eyebrows. This is where your hat normally rests. If you don't have a tape measure, you can use a piece of string and then measure it against a ruler. If you are unsure or are between sizes, always go for the larger size. As you sweat in it, the cap will shrink a bit.
