'Sweatshirt' is about how when people leave each other behind, they might leave behind something with sentimental value or something random. Whatever it is, it's the last thing in your life that reminds you of them. Sometimes it's hard to really let go all the way. The chorus brings on nostalgic feelings of relationships as well as the pop rock scene of the early 2000s.
