100% of our organic cotton is GOTS certified 

(Global Organic Textile Standard)

GOTS certified organic cotton is great! It reduces our environmental footprint by:

  • Ensuring no toxic chemicals and fertilisers are used when growing it. This means rivers, lakes and drinking water are kept cleaner.
  • Using 88% less water and 62% less energy to grow than conventional cotton.
  • Sustaining the health of the soil it grows in. The soil can then act as a sponge, soaking up water during periods of high rainfall and holding it in for longer in times of drought.
  • Helping you to choose a more sustainable alternative to conventional cotton.

We’re now GOTS certified!

After a lot of hard work, we as a brand became fully GOTS certified! This means that every step of our process has been certified, from processing, manufacturing, packaging, labelling, and trading to distribution.

Not many actual clothing brands are fully certified – it’s a huge step on our journey to driving more sustainable and responsible production as a brand.


We use polyester made from recycled bottles

Recycled Polyester is better than virgin polyester because:

  • It can help to save plastic bottles from ending up in landfill or the sea.
  • All of our recycled polyester is GRS certified.
  • Less energy is used to create polyester yarn from recycled bottles than is needed to create brand new polyester yarn from fossil fuels.
  • Recycled polyester can be recycled a number of times, helping to keep it in use for longer.

Like all of us humans, nothing is perfect:

All polyester garments shed microfibres when washing them, but there is something we can do to help prevent this - use a guppy bag to catch the microfibres, we sell them at a small loss to keep the price accessible, get one here.


Linen is great because:

  • It’s a natural fibre, made from flax plants
  • Flax is resilient and can grow in poor soil, using far less water in its consumption that cotton
  • It’s a strong, durable and long-lasting fabric 
  • It’s great in hot weather as it absorbs moisture without holding onto bacteria

We only use responsibly sourced Viscose:

  • All of our Viscose is sourced through LENZING™ ECOVERO™ and Birla Cellulose™, and are 100% certified, ensuring the fibres are derived from sustainable wood pulp.
  • The manufacture of LENZING™ ECOVERO™ fibres has a low environmental impact, generating up to 50% lower emissions and water impact compared to generic viscose. 


Bold colours & prints all dyed responsibly to Oeko-Tex & GOTS standards 

Oeko-Tex sets out strict criteria for the human AND ecological impact of all areas of production of the textiles - 
from yarns and pre-treatments to dyes and finishing chemicals. 

All of our suppliers’ mills are Oeko-Tex certified, and so only use dyes which are certified according to Standard 100 Oeko-Tex. All products which carry the Standard 100 label have been tested for harmful substances and ensure the product is harmless for your health (this is also in line with our GOTS certification).


So what on earth are natural earth dyes? 

Natural earths are mineral substances found in nature all over the world. Over time, these substances develop their own unique characteristics and colours.

Natural earth pigments are the vivid colours that come from these minerals – think yellow ochre, light sienna or rich red earths.

The best part? They have minimal environmental impact compared to the production of synthetic dyes. 

What does it mean for your Yaks?

Each piece has been individually hand dyed in India and is completely unique.

Due to the natural dye process on this garment, we recommend a delicate wash and avoiding contact with light coloured fabric in case there’s some colour transfer. 

To prolong its life, wash separately inside out on a cold wash with a low spin cycle. Dry promptly and iron cool on reverse.

Meet our dyes

Stone green
The origin of this gorgeous green is still debatable, but it was either formed in shallow waters or by volcanic rock altercations!

Light Rose
This lovely light pinkish colour comes from red earth clays, which can be found in sunny Verona.

One of the more well known pigments, charcoal is used by artists the world over, and comes from black earths that were used in the past to colour walls.

A darker pigment than Ochre, umber has earthtones that range from cream to brown, and has been used for centuries as a natural pigment (now it’s used on your Yaks!)

Ocean Earth
This beautiful blue pigment is made by crushing minerals including Lapis Lazuli and its close relative Ultramarine (In Renaissance Europe, Lapis Lazuli was super expensive thanks to its rarity!)
