The gap between how good your code is and how bad your merch is — that gap has a name. Time to close it.

// the dev wardrobe audit nobody asked for

Every developer has three kinds of shirts they're not wearing.

// error 01

The Conference Tee Pile

15 of them. All free. All boxy. The design is a company logo or a pun that stopped being funny the first time you read it. They live in a drawer that hasn't opened since 2022.

// error 02

The Amazon Impulse Buys

"Programmer" in Impact font. A CPU diagram. "I fix bugs" with a cartoon mosquito. Designed by someone who learned what a developer is from a LinkedIn post.

// error 03

The Redbubble Era

Looked great in the mockup. Arrived looking like it was ironed onto a paper bag. After 3 washes: cracked. After 5: promoted to car-cleaning rag.

// the fix

i test in PROD shirt

For the engineer who ships to production first and apologizes to staging later. If you know, you know.

// common questions

The objections, answered.

Why does it cost more than Amazon?

Ring-spun cotton vs. basic Gildan. DTG ink-in-fiber vs. heat transfer on top. You'll replace an Amazon shirt 2–3 times before this one shows any wear. Better math over time.

How does the fit run?

True to size with a modern, clean silhouette — not a boxy free-tee, not spray-painted-on. Full measurements on the product page. If it doesn't fit right, we'll sort it.

Will the print crack after washing?

DTG ink embeds into the cotton fiber — it stretches and moves with the fabric. Wash cold, tumble dry low. 100+ washes before any fade. That's the whole argument against screen print.

Where can I find return information?

Read the current refund policy before ordering. For an order issue, contact support with your order details.
