Why You'll Love This

The Certified Overthinker design celebrates thoughtful hesitation and quiet humour. Featuring a clean stamp-style look and our signature moose, it’s made for people who analyze, reflect, and replay conversations in their head — just one more time.

Subtle, relatable, and easy to wear, this design pairs naturally with Approved Decision Maker t-shirts or stands confidently on its own. Available as a sweatshirt for a cozier option.

  • Fabric weight: 4.2 oz./yd.² (142 g/m²)

Washing Instructions
