  • Classic, boxy fit with a heavier, more structured feel.
  • Wider sleeves and a roomier body create a traditional silhouette that doesn’t taper.
  • Heavyweight cotton holds its shape and feels more substantial than standard options.
  • Runs true to size for a loose fit. Size down if you want a more fitted look, especially for smaller frames.
