Design Details

- Branding: Screen-printed Mark Rober logo in a bold, clean font. The logo is centered on the chest, about palm-sized. Available in multiple colors.
- Pre-shrunk: No surprises after the first wash. Follow the care tag and it stays true to size.

|---|---|---|---|

Styling Tips
- Casual everyday: Pair with jeans or shorts and sneakers. The classic tee is a no-brainer for almost anything.
- Layer it up: Wear under an open button-down or a zip-up hoodie for a more styled look.
- Tucked in: For a retro vibe, tuck it loosely into high-waisted jeans or chinos. Add a belt to complete the outfit.
- Gym or hiking: The 100% cotton is breathable but not moisture-wicking. For heavy workouts, you might prefer a synthetic tee, but for light activity it's great.
- Color coordination: The shirt comes in black, white, navy, and heather grey. White pairs with everything; black matches any hoodie; navy keeps it subtle; heather grey is a modern classic.
