Our natural materials

Flax

Linen has many qualities. Symbol of elegance, it is resistant, absorbent, and sustainable. As a thermoregulator, it is ideal all year round. In summer, it is comfortable to wear and brings freshness. In winter, it retains heat. The cultivation of linen is respectful of nature as it requires very little water and no pesticides. It grows locally, mainly in the north of France and in Belgium.

It is used to make our jackets and pants and our bi-material accessories. We use certified linen Master of Linen.

Organic cotton

It combines comfort, flexibility and softness. He is grown without pesticides, insecticides or chemical fertilizers which are toxic to living things and pollute the environment. Its culture is therefore more ethical and more environmentally friendly than its conventionally grown counterpart.

It was selected to make the shoulder pads, which are usually made of polyester. BY JO shoulder pads are custom-made in 100% organic cotton: sewing thread, wadding and outer fabric. We use certified cotton cotton.

Olive wood

Renowned for its durability and robustness, olive wood, cultivated in Italy, was chosen for the buttons.

The color of the wood and the veins being specific to each tree, each button is unique and is engraved with the brand logo.

Our innovative materials

Eco Vero viscose

Made from wood cellulose, this soft, silky and shiny material constitutes a perfect ethical alternative to silk. Cellulose comes from sustainably managed, certified forests FSC.

Viscose is used for tailors' linings and accessoiries.

Cupro

Made from cellulose from cotton waste, this soft, fluid and satiny material also constitutes a perfect ethical alternative to silk. It is manufactured in a closed circuit thus ensuring a clean and controlled process.

Cupro is used for linings of printed suits. He is certified RCS.

Recycled polyester

Polyester is a synthetic fiber that comes from petroleum. This material is omnipresent in the fashion industry. In order to do without it as much as possible, BY JO has selected recycled polyester when a more ecological alternative without synthetic fiber does not yet exist.

Recycled polyester is used to iron-on certain parts of our suits, such as the collar or the bottom of the sleeves. 

Traditional interlining by hand (in wool and horsehair) to completely avoid iron-on is possible but for our young brand this represents a very long and difficult process to set up. We hope to develop a 100% plant-based interlining for our future collections, as materials of animal origin are prohibited at BY JO.

Our sewing thread is made of polyester. We are looking for a more ecological alternative.

An ecological textile printing

BY JO works with a Meilleur Ouvrier de France in textile printing. Via an ecological industrial printing process, it meticulously transcribes on our fabrics the work of the artists we collaborate with. This process is a “living” process: depending on the amount of ink used on our fabrics, the feel may vary slightly from one part of the pattern to another. The inks are GOTS (Global Organic Textile Standard) certified.
