How we fix fast fashion.
A Message from our founders
When we were in our very early twenties, we went to those big, cheap fashion stores everyone knows (let’s not name them). We loved fashion, we loved new outfits - we didn’t frame it like that back then, but we definitely had a thing for fast fashion. It was easy, it was fun.
It started with headaches from the fumes in the stores. Later, at university, we learned a lot about fabrics, the limits of our planet’s resources, supply chains and how toxic the industry was.
When a big Swedish fast fashion brand announced a new label with better quality, higher prices, and - duh - therefor new supply chains, we were convinced they were finally launching a more sustainable fashion brand. From everything we had learned, it seemed impossible not to.
But what they launched was a whole other story. The items were pretty, and we liked the style. But neither the fabrics nor the manufacturing conditions seemed to matter.
And that was when (while having some wine) we thought, “Well, if they’re not going to change the fast fashion system, then we’ll have to do it ourselves.” That was right after we finished university - definitely more educated than in our first semester, but still wildly naive and pretty optimistic.
Fast forward eleven years later: Although we are rooted in the idea of being a better fashion brand, caring about the fabrics we choose and the people who are involved in our supply chain, we know we are still far from perfect. Fixing fast fashion isn’t a one-time goal - it’s an ongoing process. We’re dedicated to learning, evolving, and doing better every day. If you want to see how we’re progressing, check out our annual reports for a detailed picture or browse this page to explore our focus areas.
There’s still so much work to be done.
Thank you for walking this path with us.
Thank you for saying #byebyefastfashion with us.

GOTS certificate
About GOTS
The Global Organic Textile Standard (GOTS) is recognised as the world’s leading processing standard for textiles made from organic fibres.
It defines high-level environmental criteria along the entire organic textiles supply chain and requires compliance with social criteria as well.
Only textile products that contain a minimum of 70% organic fibres can become GOTS certified.
All chemical inputs such as dyestuffs and auxiliaries used must meet certain environmental and toxicological criteria. The choice of accessories is limited in accordance with ecological aspects as well. A functional waste water treatment plant is mandatory for any wet-processing unit involved and all processors must comply with minimum social criteria.
JAN 'N JUNE has been certified since May 2021, and our very first manufacturer in Poland has been included under our certification since 2022.
Our Materials
Natural fibers
Recycled Cotton
Organic Cotton is amazing but when it comes to our world’s resources, we have to be aware that water and field land are limited. Cotton, also the organic version, does need both – and a lot of it.
For that reason we need other options. One of them is recycled cotton. In comparison to polyester or polyamide, cotton is recycled mechanically. The process is more difficult and still not widely spread. Meaning: It is generally easier to find fabrics from organic cotton than from recycled.
We're committed to expand the use of recycled cotton and introduced a jersey fabric in 2025 that is 50% recycled cotton (and 50% organic cotton).
We rate recycled cotton with A - Best.
Organic Cotton
Organic cotton makes up only a small share of global production - around 2%.
It’s usually grown using crop rotation and without synthetic pesticides or fertilizers, which helps protect soil health and biodiversity.
While organic farms often rely more on rainwater than irrigation, actual water use varies greatly by region.
Conventional cotton, which dominates the market, is often grown in large-scale monocultures and tends to depend on chemical inputs and irrigation systems.
We rate organic cotton with B - Better.
In 2023 67% of the fibers we used was organic cotton.
(Organic) Linen
Good news: Linen is naturally a low-impact fiber, but not all linen is created equal. Here’s how we categorize and rank different types of linen based on traceability, farming methods, and overall impact:
Organic Linen: Grown without synthetic fertilizers or pesticides, often with strong transparency and lower environmental impact.
We rate organic linen with A - Best.
Belgian Linen™ : Flax that is grown in Belgium and known for its high quality. However, the “Belgian” label refers to the origin of the flax and the weaving process, not necessarily where the yarn is spun. This step may still take place outside Europe. While not always organic, it’s quite well-regulated and traceable.
We rate Belgian Linen™ with B - Better.
EUROPEAN FLAX®: Grown in Europe under the European Flax® standard, which requires no irrigation, no GMOs, and mechanical fiber extraction (scutching). The standard also includes traceability through key processing steps like harvesting, retting, scutching, spinning, and weaving - all of which must be certified and audited annually
We rate EUROPEAN FLAX® with B - Better.
Recycled Wool
Recycled wool is made by reclaiming fibers from post-consumer sources (used wool garments) and/or pre-consumer sources (production scraps and offcuts).
This reduces the need for new raw materials and helps divert textile waste from landfills.
The process uses less energy and water compared to producing virgin wool, while still preserving the natural qualities of the fiber.
Because it extends the life of existing materials andand avoids the environmental impact of new wool production, we rate recycled wool as A - best option if it is GRS-certified.
Organic Wool
We only consider wool a better option (B) when it meets the standards of GOTS (Global Organic Textile Standard) or RWS (Responsible Wool Standard).
GOTS-certified wool comes from sheep raised on organic farms without synthetic pesticides or chemical treatments. It also guarantees traceability through the entire supply chain, from farm to finished product, and includes strict rules on chemical use, environmental management, and fair working conditions. GOTS-certified wool shall come from mulesing-free sources
RWS-certified wool focuses on strong animal welfare and responsible land management. It ensures sheep are treated ethically (no mulesing, proper shearing, pasture access) and that farms care for soil health and biodiversity. RWS also includes full supply chain traceability but does not necessarily require organic farming.
Recycled Cashmere
Recycled cashmere is made by reclaiming fibers from post-consumer sources (used cashmere garments) and/or pre-consumer sources (production scraps and offcuts).
This process reduces the demand for new raw materials and helps keep valuable cashmere fibers out of landfill.
Compared to virgin cashmere, recycling uses less water and energy, while maintaining the softness and quality cashmere is known for.
Because it extends the life of precious materials and reduces environmental impact, we rate recycled cashmere as A - best option (if GRS-certified)
Recycled Mohair
Recycled mohair comes from reclaiming fibers sourced from both post-consumer (used mohair garments) and pre-consumer (production scraps and offcuts) materials.
This approach reduces the need for virgin mohair and helps keep textile waste out of landfills. Recycling mohair uses less water and energy compared to producing new fiber, while maintaining the characteristic softness and sheen mohair is known for.
Because it prolongs the life of these valuable fibers and minimizes environmental impact, we rate recycled mohair as A – best option when it carries GRS certification.
Alpaca
Lightweight, warm, and hypoallergenic, alpaca offers unmatched comfort and softness.
Alpaca farming has a rich heritage in Peru, where communities have raised and cared for these animals for thousands of years, preserving traditional knowledge and sustainable practices.
Our alpaca supplier is a proud member of the International Alpaka Association (IAA), ensuring ethical practices and exceptional fiber quality every step of the way.
We rate Alpaca with B - Better.
regenerated fibers
Tencel™ Lyocell
Tencel™ Lyocell is a trademark owned by the company Lenzing. The general name of the fiber is Lyocell.
Its production process uses a closed-loop system that recycles the solvent and water. The fiber is made from wood sourced from sustainable forestry. While the process is similar to viscose, it is much more sustainable due to these closed-loop practices.
Lyocell is neither a natural nor a synthetic fiber because, although it originates from natural cellulose in wood, it undergoes significant chemical processing to turn it into fiber.
Unlike natural fibers like cotton or wool, which come directly from plants or animals, and synthetic fibers like polyester, which are petroleum-based, Lyocell sits in between - it’s a man-made regenerated cellulose fiber.
We rate this fiber with B - better.
SEACELL™ LT
SEACELL™ LT is a regenerated cellulose fiber made from seaweed and wood pulp, developed by the company smartfiber AG. The seaweed - typically sourced from Iceland - is harvested carefully to retain its natural minerals, and the fiber is produced in a closed-loop process, similar to lyocell. This means the solvents used in production are largely recovered and reused.
The result is a soft, breathable material that feels similar to lyocell, with the added benefit of incorporating seaweed.
Because it’s made from natural sources but chemically processed, SEACELL™ LT is neither a natural nor a synthetic fiber, but a regenerated fiber.
We rate it with A – best option.
Tencel™ Modal
TENCEL™ modal is a fiber developed by Lenzing and made from beechwood pulp, mainly sourced from forests in Europe. It’s known for being soft, smooth, and breathable, making it popular in garments that are worn close to the skin.
Modal is a regenerated cellulose fiber — it comes from natural wood, but is chemically processed to become a textile. So, like lyocell and viscose, it’s neither a natural nor a synthetic fiber, but something in between.
The main difference between TENCEL™ modal and TENCEL™ lyocell lies in the production process. Modal uses a slightly older method that’s less closed-loop than lyocell. While Lenzing’s modal production is more efficient than conventional viscose (using less water and energy), it doesn’t match lyocell in terms of solvent recovery and overall environmental performance.
We rate this material with B - better.
LENZING™ Ecovero™
Lenzing™ Ecovero™ viscose is a trademarked type of viscose fiber produced by Lenzing.
It is made from wood pulp sourced from certified, sustainably managed forests.
The production process uses up to 50% less water and generates up to 50% fewer greenhouse gas emissions compared to conventional viscose, making it a more environmentally friendly option.
Like Lyocell, viscose is neither a natural nor a synthetic fiber. It is a regenerated cellulose fiber — derived from natural wood pulp but chemically processed to create the fiber.
We rate this fiber with B - better.
CIRCULOSE®
CIRCULOSE® is a material made from 100% recycled textile waste, mainly old cotton garments.
Developed by the Swedish company Renewcell, it’s processed into a cellulose pulp that can be used to produce fibers like viscose, lyocell, or modal - reducing the need for virgin cotton or wood pulp.
The process is both mechanical and chemical, but avoids toxic substances and keeps the input traceable. CIRCULOSE® helps extend the life cycle of textiles that would otherwise be discarded.
We rate CIRCULOSE® with A – best option.
Enka ® Viscose
Enka ® Viscose is a regenerated cellulose fiber made from wood pulp, produced by the German company Enka. Unlike many viscose producers, Enka sources its raw materials from certified European forestry and maintains a relatively transparent supply chain.
However, the production process still relies on older viscose technology that uses chemicals and generates waste, without the closed-loop systems seen in lyocell or newer alternatives.
Because of these limitations, we rate Enka ® Viscose with C – could be better.
Bemberg™ Cupro
Bemberg™ Cupro is a regenerated cellulose fiber made by the Japanese company Asahi Kasei. It’s produced from cotton linter, a by-product of cotton processing that would otherwise go to waste.
The fiber is created using the cuprammonium process, where the cellulose is dissolved in a solution of copper and ammonia. Asahi Kasei uses a closed-loop system to recover and reuse these substances, with high solvent recovery rates.
While Bemberg™ gives value to a waste stream and the production is tightly controlled, it still relies on resource-intensive chemical processing. That’s why we rate Bemberg™ Cupro with C – could be better.
synthetic fibers
Recylced Polyester
Recycled polyester is made by melting down existing plastic — most commonly used PET bottles— and spinning it into new fibers. This reduces the need for virgin fossil resources and helps divert plastic waste from landfills or oceans.
However, most recycled polyester still comes from bottle-to-fiber systems rather than actual textile waste. It also sheds microplastics during washing, and the recycling process itself can be energy-intensive. Additionally, it’s not easily recyclable again once turned into fabric.
Because of these limitations, we rate recycled polyester with C – could be better (if it is GRS-certified).
REGENERATED Polyamide
ECONYL® regenerated polyamide is made by reclaiming waste like fishing nets, industrial scraps, or old carpets.
Instead of relying on virgin polyamide, which is made from fossil fuels, ECONYL® regenerated polyamide is GRS certified and gives waste a second life while reducing the need for new resources through a chemical recycling process.
The process can be resource-intensive, and the fiber continues to shed microplastics during use and washing.
That’s why we rate regenerated polyamide — including ECONYL® — with C – could be better.
Conventional Elastane
Conventional elastane is rated D – do not use whenever possible.
That said, elastane plays an important role in making clothes fit better and last longer. Without it, garments often wear out faster or need more frequent washing due to stretching, especially around knees and elbows. Elastane also helps clothing adapt to different body shapes for better comfort.
We use it thoughtfully when durability and fit really matter.
Manufacturing
Relationships
In an industry that often chases the next better or cheaper thing, we try to do the opposite.
For us, stability and trust matter more than jumping at short-term deals.
We believe that building long-term relationships - whether with manufacturers, suppliers, or other partners - leads to better outcomes for everyone involved. Once we start working with someone, we don’t walk away easily (Sorry not sorry!).
We rarely change manufacturers and prefer to grow together over time.
This consistency allows us to understand each other better, improve gradually, and ensure reliable quality. It also means we can have honest conversations when things go wrong - which, let’s face it, sometimes happens in real life.
We’re not perfect, but we believe in sticking around and showing up - not just when it’s easy, but especially when it’s not.
