Nau's Ten Textiles

March 24, 2022

We all face challenges in making choices that are right for the environment.  It can be difficult to know if your purchases are truly green. How can you tell if your clothes are sustainable? One step would be to look at the label.  

Our partner, Nau, is committed to creating apparel with sustainable textiles.  They use 10 fabrics—which all carry environmental certifications—in most of the clothing they make.  Read through the list and look for these fabrics while shopping our Nau Renewed Collection.



Nau invented a better way to make jackets waterproof. Their PFC-free DWR has become the industry standard for healthy, effective waterproofing.

Alpaca Wool

Alpaca wool is equally luxurious with a fraction of the impact. Nau’s partners raise Alpacas sustainably and ethically on family farms in the Peruvian Andes.

Organic Cotton

Organic cotton uses less water than conventional cotton and is grown without toxic pesticides.

Recycled Down

In 2015, Nau became the first apparel brand to introduce a recycled down collection. Starting with reclaimed duvets and pillows, the down and feathers are removed, cleaned, and then sorted according to their quality. Allowing Nau to select recycled down with identical performance characteristics as virgin down.

Merino Wool

Merino wool is the name for fine micron wool grown by merino sheep. It has the high performance Nau demands — with the soft comfort of wool. Humanely raised by small farms,we use certifications and supply chain monitoring to ensure fair treatment.


Linen grows in a way that makes it naturally sustainable. It requires little water and no pesticides to thrive, and it doesn’t use much land to grow.


Hemp is an incredibly resilient plant. It requires little water, no pesticides or fertilizers, and actually improves the quality of the soil it grows in.

Tencel and Tencel Sun

Tencel is a cellulosic fiber — woven from sustainably managed forests. Manufactured in a closed-loop process that dramatically reduces waste. Tencel has the performance of a synthetic with its breathable feel and durable wear. Tencel Sun provides UPF-30 protection.

Recycled Polyester

From plastic water bottles, industrial waste, and old garments, comes quality performance wear. When you mix recycled polyester with a bit of virgin polyester — you get the same high-quality performance. 


MicroModal is made of renewably-grown beech wood trees. It has the softness of silk and the breathability of cotton. Its closed-loop manufacturing process dramatically reduces waste and energy use.

We are proud to be in partnership Nau and so pleased The Renewal Workshop can support their journey toward Circular.
