Our Materials

Sustainability is a broad and complex concept. Perceiving sustainability as only one path is wrong since both zero waste, circularity, organic farming, local development or even empowerment of weakened communities in other countries are sustainable concepts and it’s often impossible to work on every aspect of sustainable development, so usually people focus on what they perceive as the best way, for them, to do so, and we guess we can call that balance. At Näz sustainability is our core, but it’s also something that we’ve been learning and improving, so we thought it would be nice to develop three lines in which our collections are divided, so it’s easier to understand what was the sustainable focus of a specific product.


If extending the life of a garment for 9 months reduces its carbon and water footprint by 20-30% each, think about using deadstock fabric to do an whole new garment. We believe using what already exists is always a better alternative to produce new.

When choosing deadstock fabrics for our collections we always take in account several things like:

  • Where it was produced – we only use deadstock from portuguese factories;
  • Quality – most of the fabrics we use are only deadstock due to an error in the color or small defects that we can overpass during our production;
  • Fibers – even though we work with deadstock we always prefer to choose natural or sustainable fibers.

See the garments from this line here.


Occasionally we can’t find every deadstock fabric we need to make a collection. Sometimes there’s a knit missing, or that fabric for that piece that we already designed. So when this happens (which, gladly for us, is not that often) we meet our partners to see what they have been producing and we always end up finding the perfect fabric to fit the collection.

Most of the times we already choose only from their ecological segment, but sometimes we find something we really like and challenge them to make even better, modifying fibers or even dyes, it’s just fun when we start designing in the sample showroom!

Meet some of the ecological fibers we love to use and check here our garments from this line.



Linen has always been a unique earth-friendly fiber because of flax – the plant from which it’s made — is an inherently eco-conscious crop. Sturdy and pest-resistant, it needs very little in the way of fertilizers and chemicals to thrive, and little or no irrigation during growth. Unlike most linen fabrics, our linen is woven in Portugal. Know more about our linen weaver.

Garments made of linen are smooth, durable and lightweight, perfect for Summer.  Check our linen garments.


Cupro is a regenerated cellulose fiber derived from cotton linter (which are unused silky fibers not used in cotton production). The solvents used to produce Cupro are made in what is called ‘a closed loop’ system, meaning the solvent is recycled until new solvent is needed. The old solvent is then recycled safely into other industries. Know more about our cupro supplier.

Cupro is breathable, hypoallergenic, resistant to stretching and can be machine washed. You can know more about our cupro here an check our cupro garments.

Organic Cotton

Organic cotton is grown without the use of toxic chemicals or genetically modified organisms. Instead, organic cotton is grown on land that has been treated and given sufficient time for at least three years for the removal of all the toxic residues of chemical fertilizers and pesticides used earlier on it. 

In short, it’s better for your skin and the planet. Organic cotton garments are thermoregulators, so perfect for both summer and winter and advised for people with sensitive skin. Check our organic cotton garments.


Lyocell is a natural and particularly sustainable cellulose fibre, because it is made from wood pulp. The fibre production itself is particularly eco-friendly as it constitutes a closed loop in which the solvent is reused repeatedly. Know more about our Lyocell supplier.

Fabrics created with Lyocell are among the softest and most high performance in moisture management to keep you cool, healthy and comfortable.  You can know more about our lyocell here, and check our lyocell garments.

Instead of using the classic plastic buttons we looked for a more eco-friendly alternative, how happy we were when we got to know Louropel, a portuguese button factory that is developing a wide range of eco-friendly buttons. They have a huge selection of beautiful buttons,  in our collections you can find recycled paper or cotton buttons, olive wood buttons (with a small CO2 emission footprint, since the wood is also portuguese) and coconut buttons, but their range also includes corn, corozo, cork and even coffee grounds.



Between 1975 and 2017 the production of textiles more than quadrupled (went from 24 million tons to 98.5 million tons), and, in U.S. alone, 16 million tons of textile waste was generated, of which only 16% was recycled and 19.6% was combusted for energy recovery.

So it’s only fair to repeat that we believe that using what already exists is way more sustainable than to produce more, the world is already damn full! With that in mind we started a partnership with some textile companies near Covilhã, where we are based. We got together with these small factories that are still working and have a deep knowledge on the art of making fabrics, and started developing fabrics and knits of recycled yarn. we were so lucky to be able to develop these completely local products – from the recycling to the weaving/knitting, finishing and sewing.

So this line of products it’s not only extremely sustainable, but is also fully traceable because the colors are sorted and the recycling process is fully mechanical, so it’s waterless and there’s no toxic waste (no chemicals nor dyes are used). And it’s close to our atelier!

You can know more about the recycling here and check which products are recycled here!
