This is not a trend. It is happening right now.

Look at the order requirements from international brands and major buyers — GRS certification, recycled content percentages, organic cotton traceability. These are moving from “nice to have” to “must have.”

1. The Global Headwear Industry Is Moving Toward Sustainability

The headwear industry is going through a material transition.

Some of Europe‘s leading brands have already made sustainability a hard procurement requirement. Patagonia’s new trucker cap uses 100% recycled materials — the front panel is NetPlus® 100% post-consumer recycled nylon (from discarded fishing nets), and the back panel is 100% recycled polyester mesh. Many EU buyers now ask for GRS certification as a standard part of their orders.

2. GRS Certification: The Most Basic and Most Important Threshold

GRS (Global Recycled Standard) is one of the most frequently required certifications in international brand procurement.

What GRS is: A certification that requires a minimum percentage of recycled content in the product, while also covering social responsibility, chemical restrictions, and environmental management.

Why brands require it: GRS provides full-chain traceability — from the source of recycled materials through the processing stages to the final product, every step is audited by a third party. For brands, having a GRS certificate is evidence that their “sustainability claims” are backed by verifiable data.

What it means if you don‘t have it: If your target clients are European/American brands or major retailers, not having GRS certification can get you filtered out at the supplier screening stage.

3. The Two Main Eco-Materials: Recycled Polyester and Organic Cotton

These are the two most in-demand and most mature eco-material categories in the industry today:

Recycled Polyester (RPET)

Source: Recycled plastic bottles and textile waste. The process involves washing, crushing, pelletizing, melting, spinning into fibers, and weaving into fabric suitable for hat production.

Advantages: Soft, durable, works well with embroidery, relatively cost-effective. Some brands are already using recycled fishing nets for nylon fabrics (like Patagonia‘s NetPlus® material).

Certification required: GRS is the baseline.

Organic Cotton

Characteristics: Non-GMO seeds, no chemical pesticides or fertilizers, soil health management, and completely pollution-free production.

Advantages: Better luster, softness, elasticity, antibacterial and odor-resistant properties, and hypoallergenic. Comfortable to wear in summer.

Certification required: GOTS (Global Organic Textile Standard) is the strictest standard in the industry.

Other Eco-Materials Gaining Traction

Hemp: Low environmental impact, durable, popular with streetwear brands

Recycled nylon/mesh: Suitable for sports caps and breathable styles

Natural cork/bamboo fiber: Plastic-free alternatives, suitable for brims and trim

RWS-certified wool: Responsible Wool Standard, for wool caps and fall/winter styles

FSC-certified materials: For natural straw hats and related fiber products

4. How Recycled Hats Are Made

Using recycled polyester as an example, the production process looks like this:

Collect waste plastic (bottles, discarded textiles, etc.)

Sort and clean by color

Shred into flakes

Process into pellets

Melt at high temperature

Spin into fibers

Weave into fabric

Manufacture into hats

What this means: Every recycled-material hat reduces petroleum dependence, lowers CO₂ emissions, and cuts down plastic waste.

5. Certifications We Hold

Below are the certifications our factory has already obtained, organized by category to make it easier for you to match them against your procurement requirements:
