Fit with Confidence – And Consciousness
At Pima Prima® we want you to feel great in your T-shirt. That’s why we offer returns if you're not fully satisfied with your size. But we’re also here to address a bigger issue: the environmental impact of returns and long-distance logistics.

Every return shipped across borders contributes to unnecessary carbon emissions and packaging waste. Our goal is to reduce this burden by helping you choose the right size the first time — through clear measurements, detailed guidance and personalized support.

The problem we’re solving:
Traditional fashion returns create up to 15 million metric tons of CO₂ emissions annually and generate tons of landfill waste. We're working to minimize that footprint — not by eliminating returns, but by making them smarter, fewer, and more sustainable.

Wait! Don’t Go Yet! 👋

Don’t leave these cozy Pima Cotton outfits behind! 😊

Codex of Cotton / The Search for Truth in Cotton


Codex of Cotton is a living record dedicated to discovering, documenting, preserving and advancing knowledge about Extra-Long Staple Pima cotton (Gossypium barbadense) — one of the world’s most significant natural fibers.

The Codex explores the history, science, culture, craftsmanship and future of Pima cotton through research, fieldwork, historical records, scientific evidence and firsthand observation.

In a world increasingly shaped by marketing claims, complex supply chains and growing distance between people and the origins of their clothing, the Codex exists to ask questions, examine evidence and pursue understanding.

The Codex does not exist to promote products. It exists to preserve knowledge. It exists to document what is known, investigate what is uncertain and contribute to a deeper understanding of Pima cotton and its place in human history.

The Eight Books of the Codex

Book I — Origins
Where Pima cotton came from.

Book II — Fiber Science
What makes ELS cotton extraordinary.

Book III — Craftsmanship
How fiber becomes fabric.

Book IV — Natural Color
The history and science of color.

Book V — Evidence
Research, testing, museums, archives.

Book VI — Future
Innovation, biodesign, emerging technologies.

Book VII — People
The individuals and communities behind cotton.

Book VIII — Stewardship
Preserving cotton, knowledge, culture, and land for future generations.

A Living Archive

The Codex is not a product catalog. It is not a marketing platform.
It is a living archive dedicated to knowledge, curiosity and discovery.
Every article, interview, field note and research entry contributes to a larger mission: preserving and sharing a deeper understanding of one of humanity’s most important natural fibers.

Our Belief

The better we understand cotton, the better choices we can make.
The more we understand where materials come from, how they are made and who creates them, the closer we come to the truth.
And every great textile begins with a fiber worth understanding.

Codex Contributors

The Codex is not written by a single author. It is built through the collective knowledge, experience, research and observations of people who share a common interest in understanding Extra-Long Staple Pima cotton and its place in human history.

Codex Contributors are researchers, farmers, artisans, scientists, historians, textile specialists, museum professionals, conservators, educators and explorers who contribute knowledge to the living record of Pima cotton.

Some contribute scientific evidence. Some preserve traditional knowledge. Some document history. Some work directly with fiber, fabric, color and craft. Others help ask the questions that lead to new discoveries. The purpose of the Codex is not to promote opinions. Its purpose is to document evidence, preserve knowledge and encourage inquiry.
Every contribution helps expand our collective understanding of Pima cotton and its cultural, scientific and historical significance.

We welcome contributions from every discipline connected to cotton, including archaeology, anthropology, history, textile science, agriculture, natural dye research, conservation, dermatology, sustainability and design.
The Codex is not a finished work. It is an ongoing journey of discovery.
Because the search for truth is never complete.

And knowledge, like cotton itself, becomes stronger when many fibers are woven together.
