On the outside, sweatshirt fleece looks like any other knit—it’s flat and maybe noticeably thicker than jersey. On the inside, it’s fuzzy. This fuzz is what distinguishes sweatshirting from French terry, which features loops on the back of the fabric, or any other knit fabric.
The fuzz is created by fleecing, which means that one side of the knit is brushed to form a nap. This is often done with wire brushes or sandpaper, depending on how the fleece is manufactured.
Sweatshirt fleece is usually made from cotton or polyester—or a blend—and it often includes spandex for better stretch and recovery. You will also find organic sweat fabric in this collection.
