Sweatshirts
Sweatshirts are arguably a type of sweater, but made of a fabric and cut similar to sweatpants. Sweatshirts are usually made from cotton, polyester, or other relatively low-cost materials. The fabric is usually of a much finer knit, with a nap on the inside surface, while more generally sweaters are made of a coarser knit with no napping. Sweatshirts are also almost exclusively casual attire, and not semi-formal as some other sweaters may be. Sweatshirts may or may not have a zipper, but are not referred to as cardigans even when they do have a zip-front. The sweatshirt is a ubiquitous part of youth culture and counterculture, easily found among hipsters or young adults.
