Built like a vintage rugby shirt, cut for a modern rotation. The Chicago Cubs Iconic Heavyweight T-Shirt by Fanatics is made from 400gsm cotton rugby jersey, the kind of dense, substantial cloth that holds its shape, deepens with every wash and earns its place in your wardrobe for years instead of seasons. A boxy cropped shape and slightly extended shoulder borrow from golden-era athletic shirts, paired with a ribbed collar that wears clean untucked. The matching Chicago Cubs mark at the chest is chainstitched in loose, open loops, the kind of slightly imperfect finish you'd find on a clubhouse warm-up from another era.
