This T-shirt was made primarily from USA cotton produced along the Mississippi River Basin. Using a method known as air spinning, the material is made by spinning cotton thread with a variable width of between 13mm–33mm. This spinning method creates a rough feel and unique crispy texture, since the torque on the outside of the yarn is strong and the inside is weak. Furthermore, the fabric has been pigment dyed and bio-washed to give it a vintage feel. The double stitch, the shape of the pocket mouth and the large size are typical details of Baseball uniforms from the 1890s. The design on the bottom of the pocket is a special specification that adds to reduce sweat from moistening the inside of the pocket. The ribbed neckline has also been changed to a polyurethane-blend binding that offers greater elasticity and prevents stretching when putting on and taking off the shirt.
