MLB Authenticated Game Used World Series Baseballs were used to make this collection of beanies knit from the 130 yards of usable wool yarn strands that are found inside a ball. Select your Team. The hat is knit in the order of the wool layers as they appear inside a baseball: outer gray, white, and inner gray. The yarn is then softened and the inside of the hat is lined with alpaca wool yarn for extra comfort. 

Crafted in Southern California, every hat is skillfully woven on a hand-operated knitting machine by a single craftsman. Each beanie comes in a MLB gift box with a story card.
