A soft, midweight hoodie that feels like a quiet nod to math lovers and late-night thinkers. The subtle pi symbol and "3.14" print sit cleanly on a heathered gray backdrop, turning a simple hoodie into something a little clever — the kind of piece you reach for when you want comfort without shouting. The lined two-piece hood adds warmth and structure. Dropped shoulders and a classic fit give it an easy, lived-in silhouette. Wear it to study sessions, casual lectures, coffee runs, or cozy evenings with a book — it blends into everyday life while carrying a small, private joke for those who notice. Ethically produced and OEKO-TEX certified, it’s a thoughtful choice for people who care about materials and fair manufacturing.
