Production Locations
- Netherlands (fabric sourcing)
- The brand does not communicate where the garments themselves are cut and sewn.
Working Conditions & Living Wages
All binders and “undeez” are handmade. TransUndeez does not share any information about who makes the products today or how many people are involved.
Its patterns are developed together with trans people, it serves the trans, non-binary and genderqueer community directly, and it runs a free binders programme for people who cannot afford one.
Materials
- Cotton
- Viscose
- Polyester
- Elastane
Packaging
TransUndeez does not disclose what packaging materials are used.
Water Usage & Chemicals
There is no information on the website about water use, dyeing, bleaching or chemical management, so we cannot assess this.
Circular Product Design
The products are material blends, which are harder to recycle at end of life.
Circular Business Models
There is no repair service, resale or take-back scheme.
The fitting locations help costumers find the right size before buying, which can reduce wrong-size returns.
Distance & Complexity of the Supply Chain
- Fabric sourcing: Netherlands
- Production location: not confirmed
- TransUndeez HQ is in the Netherlands.
Transportation
There is no information about how products or fabrics are transported.
- No animal-derived materials listed
Product Design
TransUndeez designs gender-affirming underwear for trans, non-binary and genderqueer people of all ages, including a kids’ range.
The patterns were developed together with the people who wear them.
Slow Fashion Processes
Everything is handmade in small numbers, and the brand has built its collection gradually since 2020 rather than dropping big seasonal lines.
The brand claims its products keep their stretch and colour well.
Transparency on Product
For each item costumers get the full material breakdown, clear washing instructions, and an explanation of how the garment is built, such as the double cotton layer against the skin and the polyester layer that creates the compression. On top of that, the pages teach costumers about safe binding and tucking: what it is, how long to wear it, health risks to watch for, and tips to protect their skin, with references to medical and scientific sources.
What is missing is traceability: the pages tell costumers what a product is made of, but not where or by whom it was made.
Transparency on Processes
The website openly shares the brand’s origin story, goes into depth on safe binding and tucking, health risks and body care, and is clear about designing its products together with the trans, non-binary and genderqueer community.
On the production side, though, traceability is only partly possible. The brand states that it sources its fabrics in the Netherlands and that everything is handmade, but it does not communicate the place of production.
Conclusion
TransUndeez is a community-driven Dutch brand making handmade chest binders, tucking slips, packers and trans swimwear, co-designed with the people who wear them. Find the products on the COSH! map below.
