This long-sleeve tee wears like an honest confession: lively, bright, and a little self-aware. A bold, colorful brain illustration sits on the chest with the words “PROFESSIONAL OVERTHINKER,” while the back carries a playful “SYSTEM OVERLOADED” graphic — a wink to anyone whose mind runs on full. The medium-weight cotton gives a vintage, lived-in feel that softens with wear. Cut in a classic fit with ribbed collar and shoulder tape for structure, it’s made without side seams for a clean silhouette and reduced waste. It’s the kind of tee you pull on when you want to wear your humor and your headspace out loud — whether you’re pacing through a late-night idea sprint, meeting friends for coffee, or just staying in and thinking it through one more time.
