Several studies claim that of the harmful climate impact generated by the production of a garment, two thirds is due to the production of the raw material.

We know for a fact that minimising the impact of production is no easy task. Sourcing raw materials requires hours of analysis, research and study of materials and suppliers.

When choosing our suppliers, we take proximity into account. For this reason, most of the fabrics we work with are made entirely in Spain. In addition, for greater transparency, they have certificates such as BCI, GOTS and GRS.

Next, you will be able to know first hand the materials with which your jeans are made.


BCI cotton

Cotton is the cornerstone of denim. Because of its comfort, durability, being a hypoallergenic material and its multiple benefits for the skin, cotton is the most widely used fibre in our garments. All the cotton we work with is certified with the BCI seal, which guarantees that it has been produced in a responsible way.

As you know, we seek to work in a sustainable way to preserve the planet, so the fabrics we use must comply with this environmental part.

Most of our jeans are dyed with Dry Indigo technology, a sustainable dyeing process that does not require the use of water.

GOTS organic cotton

As it is a natural fibre, it does not come from genetically modified seeds and no pesticides or chemical fertilisers are used in its cultivation. For us, making clothes with organic cotton is a commitment to the environment as it respects natural resources and the ecosystem.

The organic cotton we work with is certified by GOTS, one of the strictest standards currently in existence. This guarantees us that, during the whole process of cultivation of this raw material, we have worked in a responsible way and that neither the farmer, the animals nor the environment have been harmed.

When you try on a garment made of organic cotton you will clearly differentiate it for being a resistant, very soft and comfortable fibre. Being a natural fibre, it is absorbent and its contact with the skin does not cause allergic reactions.

GRS recycled cotton

As we have told you in our circularity section (if you haven't had a look at it yet, we recommend you to go and read it), giving things a second use is also one of our tasks. That's why, a few years ago, we decided to go one step further and bet on recycled cotton, thus our Ecolojeans collection was born, jeans made from other jeans that have already been discarded.

Just like organic cotton, all our recycled fabric is certified with GRS or Global Recycled Standard. This seal ensures that the yarn is recycled and that the manufacturing process has been carried out in a way that respects the environment and the people who have worked on the fabric.

_Cellulose fibre

Cellulose fibre, Lyocell, or better known as Tencel, one of the leading brands in this fabric. Currently, it is one of the most sustainable materials we can find in the market, as it is a cellulose fibre regenerated from the bark of trees. These low-impact renewable fibres are increasingly being used as they are environmentally friendly.


Typically, this pulp is extracted from eucalyptus and beech trees from certified responsibly managed forests. This ensures that the pulp is not obtained from trees that have been genetically modified for harvesting.

One of its advantages is that, as it is such a pure fibre, it does not need to be bleached and this means that very little energy is used to dye it. If you have at hand a garment made with this fabric, you will see that it is brightly coloured, very beneficial for the skin, extra soft, comfortable and very absorbent.

_Recycled polyester

Polyester is a synthetic fibre alternative to cotton that does not wrinkle or deform. Although it is not a natural fibre, it has many advantages and in order to use it in the most sustainable way possible, we have started to incorporate recycled polyester in our garments. In this way, we avoid producing more unnecessary polyester and give a second life to all that material that has already been used.

As you know, there is nothing more sustainable than what already exists, that's why, being a recycled material, we can ensure that this raw material is one of the most sustainable on the market. To guarantee that our brand is as transparent as possible, the recycled polyester we work with also has the GRS seal.

This fabric is made from the collection of used bottles, which after being transformed into PET, are spun into fibre. In addition, the PET is injected with colour and the fibre is pre-dyed.

_Biodegradable material

One of our objectives is to be able to manufacture garments that are 100% biodegradable, that is to say, from the fabric, the thread, the zip, ... For this reason, we have started to incorporate olive wood and coconut bark buttons to our garments.

Specifically, coconut fibre is a very hard material composed of cellulose and wood. Moreover, this fibre has low heat conductivity, is antimicrobial and resists water very well, so washing garments containing coconut bark is not a problem.

In addition, the collection of these materials and the manufacture of the buttons are simple processes that do not require high energy consumption.


_Other materials

Sometimes we work with natural fibres of vegetable origin such as hemp or flax. The production of these two types of materials is very energy efficient. Both are biodegradable and have benefits such as the softness and versatility of the garment. They are also fabrics that adapt to temperatures and have the ability to absorb moisture.

Natural, organic, renewable.
