Our material selection focusses on choosing the right fabrics to create the best product we can; product that lasts, is fit for purpose and has the least environmental impact possible.
Why we love Natural Fibres...
Natural fibres are the perfect material to use for next-to-skin products. They are incredibly versatile, providing softness and strength as well as being good insulators, breathable and sweat wicking. They're also completely renewable, so the fibre can be replenished again and again.
In 2017, we made a commitment to reduce our reliance on conventional cotton and increase our use of alternative natural fibres, which require reduced water and pesticides to grow. In 2017 only 42% of our cotton range was organic, so we set ourselves the goal that by 2020 our entire cotton collection would be organic. But we're always striving for better, and we have now increased the use of natural fibres across our product range; widening our use of wool, linen, hemp and also kapok.
Linen: The original fibre
Linen is the natural fibre derived from the flax plant. It is thought to be one of the oldest textile fibres in the world, most notably used by the ancient Egyptians. Linen fabrics are durable, long-lasting and soften over time, ageing with you. It’s an incredibly comfortable fibre to wear next to your skin, with a cool, smooth touch and, like wool, linen regulates temperature, so it’s cool and breathable in summer and insulating in winter.
It has a host of sustainable benefits too; the cultivation of flax requires no fertilisers, herbicides or pesticides and no irrigation (only rainwater) to grow. Plus, flax encourages biodiversity where it’s grown and is waste-free, as all parts of the plant can be used for textiles, food, paper and bio-oils.
Hemp: A fibre for the future
Like linen, hemp has been cultivated for thousands of years - one of the oldest relics of human activity is a piece of hemp fabric dating back to approximately 8,000 BC. It’s highly absorbent and can be blended with other natural fibres like cotton to create a soft but far more durable fabric.
In fact, hemp is six times stronger than cotton and far less intensive to cultivate. It is one of the highest yielding crops on the planet, but actually requires very little water and no chemical fertilisers or pesticides to grow. It even blocks weeds from growing, making it a great option for farmers to improve soil quality, and different parts of the plant can be used to make tens of thousands of products – not just textiles.
Kapok: The world’s most sustainable fibre
Kapok fibres come from the seed pods of the Ceiba Pentandra, a tropical tree sustainably harvested in the rainforests of Asia. Incredibly light, soft, and buoyant, the material has many of the same properties of down and is sometimes referred to as silk cotton due to its fineness. It requires very little water or pesticides to grow and virtually no processing for fibre production - it's widely considered to be the most sustainable fibre on the market.
The only downside to the fibre is (ironically) its softness, which mean it is almost impossible to create a pure Kapok yarn. Blended with other fabrics though, it comes into its own, adding incredible softness to the material whilst cutting down considerably on water consumption. For example, if 1kg of cotton can produce 4 t-shirts, a 70:30 cotton/kapok blend will do the same, and save you 3000 litres of water.
Bamboo: A technical fibre from trees
Bamboo has a host of natural properties that make it a fantastic fibre for clothing. Breathable, temperature regulating, antibacterial, moisture wicking, hypoallergenic – we could go on but we’d be here a while. Add to this its super soft texture and incredible comfort next to the skin and you’ll see why we love it.
It’s also one of the most renewable fibres on the planet. Fast growing, it requires very little water and no pesticides, removing as much CO2 from the atmosphere during growth as is created when it’s harvested.
