Description

The ultimate low-effort Halloween costume: a clever nod to the classic 404 error. Perfect for programmers, gamers, or anyone who loves tech humor. Offered in both mens and womens fits.

Fit & Features

  • The tee you’ll reach for every day — soft, breathable, and built for lasting comfort. Made from soft-style midweight fabric with a modern classic fit, and has a soft finish you’ll love to wear. After printing, each item is cured under high heat to prevent fading and flaking.
  • Material:
  • Black: 100% Ringspun Cotton
  • Sport Grey: 90% Ringspun Cotton / 10% Polyester
  • Care: Machine wash warm, tumble dry
  • Fit: Predominantly true to size. If in between sizes, we recommend going up one size as garments shrink 1–2%.
