About this design
Here I am, brain the size of a planet, and you're wearing a t-shirt.
Pay tribute to the galaxy's most gloriously gloomy robot with this Marvin the Paranoid Android anatomical diagram t-shirt, inspired by Douglas Adams' legendary Hitchhiker's Guide to the Galaxy. Featuring an intricate blueprint-style design that maps out Marvin's inner workings — from his planet-sized brain to the circuits responsible for his unmatched pessimism — this is wearable sci-fi art for the chronically underappreciated.
Comfortable, unisex, and dripping in cosmic melancholy, it's the perfect conversation starter for fellow Hitchhiker's fans, lovers of dry British humour, and anyone who relates just a little too much to Marvin's existential outlook on life, the universe, and everything.
- Unisex fit, premium quality print
- Ideal for everyday wear or geeking out at conventions
- A gift they definitely won't find disappointing (unlike Marvin finds everything)
Don't panic — Marvin will do enough of that for all of us.
Perfect for: Hitchhiker's Guide to the Galaxy fans, Douglas Adams gifts, Marvin the Paranoid Android merchandise, sci-fi t-shirts, robot t-shirts, geeky gifts for him, geeky gifts for her, Towel Day gifts, nerdy birthday gifts

Everything you need to know before you buy
We print on the Gildan Heavy Cotton T-Shirt — 100% pre-shrunk cotton jersey at 185gsm for colours (175gsm white). It's soft, substantial, and holds its shape wash after wash. Comes with a seamless twin needle collar, taped neck and shoulders, and a tear-out label for comfort.
Yes. The Gildan Heavy Cotton is WRAP certified, SEDEX certified, Oeko-Tex certified, REACH certified, and Fair Labour certified. So you can wear it with a clear conscience.
Machine wash inside out at 30°C or below. Avoid tumble drying on high heat. Don't iron directly on the print. Washing inside out helps preserve the print colour and keeps it looking sharp for longer.
We do our best to ensure product images are as true to life as possible, but screen colours vary by device and we can't guarantee an exact match. If colour accuracy is important, we'd suggest ordering a single item first.
Yes — add a personal note in the order comments at checkout and we'll include it with your order at no extra charge.
The Gildan Heavy Cotton is a classic unisex fit — not slim cut. It comes up true to size and is pre-washed so it won't shrink significantly after purchase. If you're between sizes or prefer a relaxed fit, size up.
All measurements in cm. Half chest measured 2.5cm below armhole.
Measurements are provided by the supplier and may vary by up to 2 inches (5cm).
| S | M | L | XL | 2XL | 3XL | 4XL | 5XL | |
|---|---|---|---|---|---|---|---|---|
| Half chest (cm) | 46 | 51 | 56 | 61 | 66 | 71 | 76 | 81 |
| Body length (cm) | 70 | 73 | 76 | 78 | 81 | 84 | 86 | 89 |
| To fit chest (inch) | 34–36 | 38–40 | 42–44 | 46–48 | 50–52 | 54–56 | 58–60 | 62–64 |
For the best fit, measure a t-shirt you already own and compare to the size chart. To measure chest width, lay the shirt flat and measure across the chest from one armpit seam to the other — that's your half chest measurement. For length, measure from the highest point of the shoulder down to the bottom hem.
Not always — some colours are only available in certain sizes. The size selector on the product page will show which options are available for each colour. If a size is greyed out, it's not available in that colour.
