Sustainable Clothing Fibers

It all starts with the best ingredients right?

We believe in creating beautiful clothing that’s kind to the planet. The biggest impact of clothing is after its production, so quality and the social consciousness of fashion are definitely on our top priorities.
Nevertheless, our founder true love lies within textile fibers so the materials we choose are a core part of our commitment to sustainability.

Linen comes from Flax trees, which can grow in poor land that is not used for food production - it can even rehabilitate polluted soil.

Rainwater is the most used way to cultivate flax, as it needs 60% less water than conventional cotton. That saves 307 litres of water per kilo of fibre compared to cotton (yes, a bit shocking).

Organic Cotton

By not using harmful chemicals, organic cotton means a healthier planet since it reduces the risk of water acidification and eutrophication.

Being mostly rain-fed, savings on water can go up to 79% and almost 60% on emissions, as a big part of cotton growing emissions comes from fertilizers and pesticides used.

Lyocell is a special fibre from Tencel®, created using a closed-loop system that recycles almost all of the chemicals used. By using it, we’re sure it comes from eucalyptus from PEFC certified forests.

Only 2 litres of water are wasted per kilo of Lyocell fiber. Plus, it has 72.5% percent lower CO2 emissions than polyester.

Recyced Materials

By choosing recycled wool, we're not only crafting high-quality products but also reducing our carbon footprint, saving 11 kilos of CO2 per kilo of fiber compared to virgin wool.

Our waterless, chemical-free, and dye-free recycling process minimizes waste. Plus, our products are fully traceable and locally made within a 50-kilometer radius, supporting a sustainable and community-centered approach. Join us on our green journey!

Deadstock Fabrics

Let's face it, we have enough fabric in the world to stop producing more right?

These fellows are leftover fabrics from textile factories who either overestimated their needs or had to produce more than they predicted due to minimum quantities orders of yarn.

Using what already exists is always better than producing new, since the impact of using deadstock fabrics that don’t need any transformation, is zero. Niente. Nichts. Zero burdens.

Products made with deadstock

Don't discriminate, they have the same quality as al of the above and even thought they were not intended to be eco-friendly, by giving them a new life they are even more.
