About the product

Soft, roomy, and quietly nerdy — this crewneck wraps you in comfort while celebrating the scale of the cosmos. The bold white type on a black sweatshirt lists the parsec definition in plain, unapologetic font: a little astronomical trivia you can wear. It feels like settling into a late-night stargazing session: warm, steady, and a touch clever. The classic crew cut and durable double-needle stitching mean this becomes a go-to layer for study sessions, lab nights, planetarium visits, or weekend coffee runs when you want to signal your curiosity without saying a word.
