What Customers Are Saying:

Why THE LAB CULT?

Apparel that thinks as hard as you do

Because science deserves better than some clip art of a beaker on a white tee. And because we'd rather wear ideas than logos. Science isn't just what we do. It's our way of seeing the world.

Our designs are for all the researchers, students, educators, amateur naturalists, and overthinkers. Anyone who looks at the world and wants to know how it works, finds beauty in a scatter plot, or laughs at a geology pun.

Our customers are smart, a bit tired, still curious...and proud of it.

FAQs

Where are you located?

THE LAB CULT is a Canadian company. All T-shirts for our Canadian customers are printed domestically in Ontario.

To better serve our US and Australian customers, we've partnered with reputable print providers in the US.

Do you ship worldwide?

As of now, we only ship to Canada, the US, and Australia, but we're working on getting our goods out to the rest of the world. Please stay tuned!

What are your shirts made of?

We print on the Gildan 64000 Softstyle® tee. Most colours are made from 100% ring-spun cotton, while heather colours and Sport Grey are cotton-poly blends. The cotton used in these shirts is sourced through Better Cotton initiatives, supporting more responsible cotton production. After testing multiple options, we found the 64000 offered the best balance of comfort, print quality, and value. If you prefer heavyweight workwear-style tees, our shirts may feel lighter than what you’re used to.

Can I cancel my order?

We print each item just for you to reduce waste and avoid overproduction. If you'd like to cancel your order, please contact us as soon as possible. If your order has already entered production and cannot be cancelled, it may be returned after delivery in accordance with our return policy.
