I love the print! And the joke in it. I got the white shirt and it's a little see through. The t shirt fabric is a little thin for the white shirt to be completely opaque.

Oh No! The Economy! T-shirt

I did not order this t-shirt. I don’t want it. You used my information to pay for a shirt I didn’t want. This happened again with another shirt I didn’t want. O

Oh No! The Economy! T-shirt

I love the design, but the T-shirt material feels a bit too thin to last long.

Oh No! The Economy! T-shirt

Love the “Economy” disaster T-shirt I got from you guys. The T-shirts are heavy cotton with great screen printing that washes well. It survived the first trip through the dryer which cheaply screen printed shirts sometimes don’t. The design is great and sarcastic but so relevant. Have gotten compliments on it already.

Oh No! The Economy! T-shirt

Love the shirts; disappointed in your use of Amazon for shipping. I do not support Amazon in any shape or form and, unfortunately, won’t be ordering from you again.

Fast delivery and lovely quality. My husband made the mistake of telling me he likes dinosaurs so now he will get at least 2 t-shirts a year from you, from me 😂 thank you for existing ☺️

My husband and I got matching bonk shirts. They fit true to size, are very soft, very comfortable and 100% cotton. Perfect length to width ratio and not boxy. Very pleased and will order more!

Everything You Need to Know

GeoCuriosity FAQs

What makes GeoCuriosity shirts different?


Each shirt is more than just apparel—it’s a story rooted in nature and science. Designed by a PhD researcher in geography who studies the geodiversity of Earth (from oceans and volcanoes to fossils and ancient landscapes), our shirts reflect a love for nature, heritage, and wild places. Every purchase plants a tree and supports sustainable, ethical production.

What is geodiversity—and how does it inspire your designs?


Geodiversity refers to the variety of Earth’s natural features: rocks, landforms, soils, water systems, and the heritage they create—known as geoheritage. From mountain ranges to fossil beds, our designs celebrate this richness and help you connect with the natural history of our planet. Geodiversity is the foundation of Biodiversity, the beauty of our planet would not exist without geodiversity!

What is the fit and quality of your shirts?


Our shirts are made with 100% ring-spun cotton (heather colors include polyester) for a soft, breathable feel that’s built to last. The fabric is lightweight at 4.5 oz/yd² (153 g/m²), offering comfort without sacrificing durability. Featuring a modern unisex fit and a seamless body for smooth wear, each shirt is made in WRAP-certified facilities using OEKO-TEX® certified dyes and ethically grown U.S. cotton.

How do I care for my shirt to keep it looking great?


Wash your shirt inside out on a cool setting with mild detergent, and air dry when possible. Avoid excessive spin cycles and iron inside out on low heat. These small steps will help preserve the vibrant colors and detailed designs—so your shirt stays fresh for every season of curiosity.

Where and how are your products made?

Our t-shirt blanks are manufactured in Nicaragua using ethically sourced cotton and certified production standards.

Printing is done locally at professional facilities closest to your location to reduce shipping emissions. Our shirts are created in:

  • United States
  • Canada
  • Latvia
  • Spain
  • UK
  • Germany
  • Poland
  • Australia

How does GeoCuriosity support conservation and the planet?

At the heart of GeoCuriosity is a deep commitment to conservation and geoheritage—the protection of Earth’s diverse landscapes and the stories they hold. That’s why every shirt sold plants a tree through our partnership with veritree via TheGoodAPI, supporting reforestation efforts around the world.

These tree-planting projects restore ecosystems, enhance biodiversity, protect coastlines, empower local communities, and increase carbon sequestration. From rebuilding mangrove forests in Kenya to upcoming projects in the United States, your purchase helps restore the Earth’s natural balance.

Our impact supports the United Nations Sustainable Development Goals, specifically:

  • #17 Partnerships for the Goals
  • #15 Life on Land
  • #14 Life Below Water
  • #13 Climate Action
  • #12 Responsible Consumption
  • #8 Decent Work and Economic Growth

Your curiosity doesn't just connect you to nature—it helps protect it.
