Summary: Breaking down the makeup of all soccer jerseys from top brands and why most use a certain material over others.
The Simple Answer:
Almost every soccer jerseys is made from 100% polyester. Now while most soccer jerseys are made from the same type of material, not all polyester is the same. Polyester is just a family of fabrics with varying styles, weights and qualities of polyester.
As described by Amanda Capritto of CNET, "Polyester is incredibly durable, wrinkle-resistant and moisture-wicking. It's also breathable and lightweight, so your sweat evaporates through the fabric and you'll stay relatively dry."
