{|x| x _ x} Developer T-Shirt (Ruby Edition — Dark Mode)

£25.00
Size

A clean, expressive nod to Ruby's elegant block syntax. This Dark Mode tee showcases the mathematical beauty of:

{|x| x * x}

A compact block that says “Ruby can be functional too,” perfect for devs who appreciate readable one-liners, smooth iteration, and code that feels almost poetic.

Soft, durable, and ideal for late-night refactors, Rails sessions, or quietly mapping over an array just to watch it transform.

  • 100% combed and ring-spun cotton (Heather colors contain polyester)
  • Fabric weight: 4.2 oz./yd.² (142 g/m²)
  • Pre-shrunk fabric
  • Side-seamed construction
  • Shoulder-to-shoulder taping
  • Blank product sourced from Nicaragua, Mexico, Honduras, or the US

Disclaimer: The fabric is slightly sheer and may appear subtly see-through under certain lighting conditions.

Printed on demand — expressive, elegant, and unmistakably Ruby.

Part of the Ruby collection, within Backend & Server.

Available in Dark Mode and Light Mode.

Heads-up

Shipping costs vary by region, so it’s worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn’t available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.

We’re constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.
