TEXTILES & TRACEABILITY.
Joslin is not a certified European Flax® brand.
Joslin's linen is certified with European Flax® through the textile mills Joslin's works with that have received European Flax® certification (as listed on 'Responsibility & Transparency' page. The European Flax® Charter, signed by all the Flax producers, guarantees local farming that respects the environment and commits to zero irrigation, zero GMO, and zero waste.
All work is done in compliance with the International Labour Organisation (ILO). The ILO is devoted to promoting social justice and internationally recognised human and labor rights, pursuing its founding mission that social justice is essential to universal and lasting peace.
Joslin's European Flax® is of traceability to the Normandy region of France and Belgium, a terroir of excellence for the flax culture and traditional agriculture that positively affects the ecosystem diversity and offers an environmental pause for soil quality and biodiversity.
From the field to the scutched fibre, the production of Joslin's linen is fully traced, which allows a better follow-up of the fibre lots quality. The combed flax is imported into a mill in Jiangsu, China, in bales where it is spun and then woven into batiste cloth.
Linen uses approximately 90% less embodied energy in its manufacture than polyester, fast fashion's most common fabric, and is long-lasting and durable in the wardrobe.
Joslin, as a brand is not certified at an organic level, with any certification body.
Joslin's Organic Cotton is verified from farm to textile/yarn stage with GOTS (Global Organic Textile Standard), in which each tier in this stage of supply is certified (as listed on 'Responsibility & Transparency' page.
Joslin is working to obtain brand certification to be able to make environmental claims on our Organic Cotton products and showcase third-party certifications via logos on our products to our community.
Organic cotton farming does not allow the use of toxic chemicals or GMOs (genetically modified organisms). Instead, it combines tradition, innovation, and science to benefit the shared environment and promote a good quality of life for all involved.
Organic cotton farming sustains the soil and ecosystems by using natural processes rather than artificial inputs.
Growing organic cotton keeps farmers and their families safe. They are not exposed to toxic chemicals in the field or through their food and water supply. It also means farmers grow more than one crop, which supplements their food and income.
GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria, backed by independent certification of the entire textile supply chain. All chemical additives, such as dyes, adjuvants, must meet specific environmental standards and toxicology standards. An effective sewage treatment plant must accompany all water treatment-related production, and all treatment equipment must meet minimum social standards.
Joslin, as a brand is not certified with GCS (Good Cashmere Standard), with any certification body.
Joslin's cashmere is verified from farm to yarn stage with GCS (Good Cashmere Standard), in which each our yarn supplier (UPW) is certified.
UPW's cashmere is sourced from ethical farms in Inner Mongolia, which are regularly monitored to ensure the best living standards of the animals. Because of unique inventory control software, all of Joslin's cashmere fibers are traceable to a specific region, down to each cone.
UPW's cashmere is certified with GCS (Good Cashmere Standard), SFA (Sustainable Fibre Alliance), and ICCAW (International Cooperation Committee of Animal Welfare).
To become certified with GCS, cashmere farmers completed a comprehensive series of questions on their livestock-keeping practices. Based on these results, independent third parties visit the farms to verify the proper implementation of the standard.
Joslin, as a brand is not certified with Responsible Wool Standard (RWS), with any certification body.
Joslin's merino wool is verified from farm to yarn stage with Responsible Wool Standard (RWS), in which our yarn supplier (UPW) is certified.
UPW's merino wool is certified by the Responsible Wool Standard (RWS).
The Responsible Wool Standard (RWS) is an independent, voluntary standard. On farms, the certification ensures that sheep are treated with respect to their Five Freedoms and provides best practices in the management and protection of the land. Through the processing stages, certification ensures that wool from certified farms is correctly identified and tracked.
Joslin does not individually certify each product to OEKO-TEX® 100 STANDARD.
Joslin's has ensured (to the best of our knowledge and supplier authenticity) that all textile and trim dye-houses ensure yearly certification of OEKO-TEX® 100 STANDARD, meaning only OEKO-TEX® 100 STANDARD chemicals are used during the dying process, ensuring customer confidence, high product safety, and healthier waterways. OEKO-TEX® undertakes extensive product checks and regular company on-site visits with factories worldwide to ensure that the industry has a globally sustainable awareness of the responsible use of chemicals.
Joslin, as a brand is not certified at a recycled level, with any certification body.
Joslin does not use any recycled polyester or plastic textiles. Joslin uses blended post-consumer recycled plastic in all button moulds for designs that have textile 'covered buttons'.
As covered buttons are a prominient feature of Joslin designs, it is important to ensure best practice.
Joslin's Post-Consumer Recycled Polyester Button Moulds are verified from raw processing stage to trading stage only with GRS (Global Recycle Standard), (as listed on 'Responsibility & Transparency' page.
Joslin is aiming to obtain brand certification for the GRS (Global Recycle Standard) to be able to make environmental claims on our post consumer recycled polyester buttons and showcase our third-party certifications via logos on our products to our community.
The Recycled Claim Standard (RCS) and Global Recycled Standard (GRS) are international, voluntary standards that set requirements for third-party certification of recycled input and chain of custody. The shared goal of the standards is to increase the use of recycled materials. The GRS includes additional criteria for social and environmental processing requirements and chemical restrictions.
Joslin, as a brand is not certified at a any FSC® level, with any certification body.
Joslin’s viscose voile lining is certified with FSC® (Forest Stewardship Council®) at raw and processing stages (with listing via our 'Responsibility & Transparency' page. The Forest Stewardship Council promotes environmentally appropriate, socially beneficial, and economically viable management of the world’s forests.
Silk is a natural protein fibre, composed mainly of fibroin and is produced by insect larvae to form cocoons.
Joslin's silk and silk garments are all produced through the one manufacturer, with a vertical operation, Wujiang Silk Garment Co Ltd in Suzhou, Jiangsu, China.
This means Joslin's entire manufacturing process of silk is traceable, from farming and harvesting, spinning and final production.
Suzhou has been at the centre of China's illustrious silk trade for centuries, and still uses ancient techniques and fine craftsmanship.
Ramie has many similar characteristics to linen, but ramie fibers are sourced from Chinese Nettle, native to East Asia.
The ramie plant grows quickly and can be harvested three to six times a year. Ramie is also grown without pesticides and is watered from rainfall alone. It is naturally growing and biodegradable.
Joslin's ramie is grown in southern China and is woven into ramie organdy and batiste cloth.
Minimal animal products are used in the production of Joslin garments. Currently the only animal products used are Cashmere, Merino Wool and Silk. Joslin stands for the prevention, reduction and eradication of animal suffering in the production supply chain and works in line with the five freedoms of animal welfare. Joslin strictly prohibits Leather, Exotic Animal Skin, Fur, Angora, Feathers and Down products in their apparel.
Joslin uses the same textiles, materials, trims, and raw materials in each collection to eliminate dead stock waste (this in no way prohibits textile waste, which is impossible in garment production).
This is why, while shopping for our products, you will see a minimal variety of fabrications used by Joslin. If one of Joslin's suppliers overbuys or overproduces a textile, the overs will be cut into the following purchase order of apparel instead of going to dead stock.
Synthetics and plastics (Polyester, Acrylic, Nylon) are not used at Joslin, although they are not 100% avoidable in garment production. Synthetic textiles are non-compostable, non-biodegradable, and have 'micro-plastic properties that profoundly affect the planet's land-fill levels and oceans. They have a negative environmental impact and carbon emissions of producing polyesters and acrylics through petroleum. In Joslin garments, synthetics and plastics are only used when there is no natural alternative, or it benefits that natural composition. It is not always possible to avoid synthetics and plastics in garment production - buttons, zips, and fusings are the benchmark of standard manufacturing and garment construction. There is currently no natural alternative that is commercially viable for fusing.
