Every Labrador owner has been thoroughly vetted — by their dog. Food: tested. Sofa: tested. Patience: extensively tested. This tee announces the verdict with a grin: a bespectacled yellow Lab in a lab coat and tie, surrounded by beakers and bubbling flasks, above the words every Lab household has earned — Lab Tested, Owner Approved. It's the pun that makes dog people groan and then immediately buy it.

The Pun That Works Every Time
The scientist Lab — glasses, lab coat, smart orange tie — sits in a teal laboratory panel that pops off light shirts. It's funny without being crude, clever without trying too hard, and instantly understood by every Labrador person you'll ever pass on a walk.
Airlume Combed Cotton
100% Airlume combed and ring-spun cotton — combed smooth before spinning, so it's soft from the first wear with none of the itch of a cheap promo tee. At 142 gsm it's light and breathable: built for fetch sessions that go on much longer than planned.
True Unisex Fit
Side-seamed construction and shoulder taping give a proper retail fit that runs true to size on men and women alike — a reliable gift for Lab dads, Lab mums, vets, vet nurses and anyone whose dog has strong opinions about dinner time. Exact measurements are in the size chart below.
Print That Lasts
The design is printed directly into the fabric, not heat-pressed on top — no stiff plastic patch to crack or peel. Washed cold and inside out, the teal lab scene and crisp lettering stay sharp through years of dog walks.

Light tee, not a heavyweight: at 142 gsm this is a soft everyday t-shirt. If you prefer a thick, boxy 220 gsm streetwear tee, this will feel lighter than you're used to.

3XL in White and Athletic Heather only: Natural and Yellow run S–2XL. No 4XL or 5XL on this design.

Light shirts only: the dark lettering and teal artwork panel need a light shirt to shine — there's no black or navy option on this design.

✅ Right for you if…
  • A Labrador runs your household's quality control department
  • You love a good pun and aren't ashamed to wear it
  • You're gifting a Lab owner, vet, or science type
  • You want a soft, light tee for everyday and dog-walk wear
❌ Not for you if…
  • You want dark shirt colours — this artwork lives on light shades
  • You prefer elegant portraits to playful cartoons
  • You need 4XL or 5XL (this design runs S–3XL)
  • You prefer embroidered designs over printed artwork

Frequently Asked Questions

Does it run true to size?

Yes — this is a standard unisex retail fit and runs true to size for both men and women. If you're between sizes or prefer a relaxed fit, go one size up. Exact garment measurements are in the size chart above.

Which colour shows the design best?

White gives the teal lab scene maximum punch. Natural adds warmth, Athletic Heather is the easy everyday pick, and Yellow is the committed choice — a yellow Lab on a yellow shirt is fully on theme.

I have a black/chocolate Lab — does it still work?

Absolutely. The scientist happens to be a yellow Lab, but the joke is universal — black, chocolate, yellow and fox-red Lab owners have all been equally lab tested and approved.

Will the print crack or fade in the wash?

No — the design is printed directly into the cotton fibres rather than pressed on top, so there's nothing to crack or peel. Wash cold, inside out, and avoid ironing directly over the print.

How long does delivery take, and what does it cost?

Delivery is free and fully tracked to the UK, EU, US, Australia and more than 40 countries in total. Anywhere else ships at a flat £6.99. For estimated delivery times to your location, see our contact page or check the information at checkout.

Can I return it if it's not right?

How do I choose the right size?

How do I care for my tee?

Wash inside out at 30°C with similar colours, and avoid ironing directly over the print. Hang to dry where you can. Treated well, the print stays bright and crack-free for years.
