The BALL PARK CREWNECK SWEATSHIRT is crafted from heavyweight 12oz cotton fabric, constructed with a four-needle flatlock sewing machine. The fabric is specially knit using a high-speed sinker knitting machine which was originally developed as a more efficient alternative to the traditional loopwheel machine. While the loopwheel is known for its loose weave and slow production, the sinker machine not only increased efficiency but also allows for the creation of denser, heavier fabrics ideal for robust, high-quality garments.

The sweatshirt, born in the 1920s in the USA, was initially conceived as practical athletic wear by Benjamin Russell Jr., a football player dissatisfied with itchy wool jerseys. Its comfortable cotton fleece soon attracted non-athletes, escalating its popularity in American colleges.
