Care Instructions

Keep Your GeoCuriosity T-Shirts Vibrant All Season Long!

Follow these tips, and your seasonal t-shirts will keep their vibrant colors longer than the changing leaves!

Wash and Dry Inside Out:

It’s a simple yet crucial step to protect the designs and colors.

Low Temperatures and Gentle Detergents:

Your shirt isn’t a summer barbecue, so avoid high heat! Opt for cooler washes and mild detergents.

Avoid Excessive Spinning:

Resist the temptation to spin excessively. Extra spins can lead to more wear and tear.

Air Dry Whenever Possible:

Air drying is the best option. If you must tumble dry, avoid heavyweight companions like winter coats and blankets.

Iron Inside Out:

Start with a lower heat setting. Designs and irons aren’t always the best of friends, so be gentle.

Keep your GeoCuriosity shirts looking fresh and ready for your next adventure!

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.
