The reasons people wear hoodies and sweatshirts come down to utility, comfort, and style. A hoodie serves a practical purpose as a mid-layer that retains more body heat. A hoodie is also very comfortable, making it a fun item to wear. It’s also fun to put the hood up over your head for extra protection or as a stylistic choice. Many hoodies also sport popular brand logos or art that you want to highlight. Sweatshirts share all of the comfort, style, and utility of a hoodie, just without the hood.
