Used underwear for men is a niche market, but it also raises a broader question: what should happen to garments when their original use comes to an end?
This guide looks at how used men’s underwear can be bought, sold, reused or recycled, with a focus on hygiene, privacy, traceability and responsible handling.
At ZLCOPENHAGEN, we also explore this from a product life-cycle and circular design perspective. Selected prototypes, fitting samples and production variations can enter a controlled life-cycle process rather than simply becoming textile waste.
WHERE TO BUY OR SELL USED MEN’S UNDERWEAR
Used men’s underwear is a niche market and may be exchanged through specialised platforms, private communities or controlled life-cycle initiatives. Requirements can vary between platforms and locations, so sellers and buyers should check the applicable rules before exchanging used garments.
SELLING USED MEN’S UNDERWEAR RESPONSIBLY
For anyone considering selling used men’s underwear, hygiene, privacy and transparency about the condition and history of the garment are important. The same principles apply to samples, prototypes and other garments that have previously been worn or handled.
At ZLCOPENHAGEN, selected prototypes, fitting samples and production variations may be considered for controlled reuse, recycling or material recovery rather than simply being discarded.
A PILOT PROJECT — COLLABORATION & CONTACT
This life-cycle initiative currently operates as a pilot project exploring how selected garments and textile materials can move beyond a conventional use-and-discard model.
We are interested in collaboration with individuals and partners who encounter surplus, archived or non-standard underwear through production, sampling, fittings or other controlled textile flows.
If you work with underwear, socks or similar textile products — or have experience with surplus materials, samples or textile waste — you are welcome to get in touch. These collaborations can help us explore practical approaches to reuse, recycling and responsible material handling.
HOW OUR CIRCULAR PROCESS WORKS
Our approach looks at the garment as part of a wider product life cycle. Depending on its condition, a garment or its materials may be considered for controlled reuse, recycling or material recovery.
The aim is to explore ways of extending useful material life and reducing textile waste while keeping hygiene, privacy and traceability at the centre of the process.
THE LIFE CYCLE OF USED UNDERWEAR
FROM GARMENT USE TO MATERIAL RECOVERY
ZLCOPENHAGEN’s life-cycle project looks at what can happen to men’s underwear, prototypes, fitting samples and archived garments when they reach the end of their original use.
Instead of treating every garment as waste, we consider different pathways depending on its condition: continued use, controlled reuse, recycling or material recovery. This creates a more systematic approach to the garment’s product life cycle.
The project connects practical textile handling with broader principles of circular design, resource use and waste reduction. Read more about our sustainable fashion and recycling approach.
LOCAL RECYCLING AND MATERIAL HANDLING
We collaborate with a local recycling station to explore responsible pathways for selected model samples, customer donations and other garments that are no longer suitable for their original use.
Items are assessed according to their condition and may be directed towards reuse, recycling or material recovery. This helps us better understand how small-scale textile flows can be managed while considering hygiene, traceability and waste reduction.
