Our sustainable materials Every new style in our collection has to meet rigorous criteria. First, it has to be a great idea that serves a purpose. Quality is paramount. It must fit well and be functional. It must also be certified STANDARD 100 by OEKO-TEX®. Last but not least, it must be made of sustainable materials. Since 2008, we have increased the use of sustainable materials from 20% to 93% (measured by weight of our total production in 2016). We aim to make that figure 100%. Here are the sustainable materials we use today: Organic cotton All cotton in our production is certified organic cotton. Organic cotton cultivation is based on long-term and sustainable methods. The cotton is grown without the use of chemical pesticides or fertilizers. Choosing organic cotton over traditionally grown cotton means making a choice that is better for cotton farmers as well as the environment. Lyocell Lyocell is a cellulose fibre made from fast-growing eucalyptus and other woods from sustainably managed forests where cultivation requires only 5% of the water used in traditional cotton farming. The fibre is produced in a closed loop process, in which almost all of the water and chemicals are reused. Recycled polyamide For our bras, tights and leggings we use Q-nova®, a yarn made from recycled industrial waste. For our swimwear we use ECONYL®. This yarn is made of post-consumer waste like old fishing nets and industrial waste that has been re-generated into new yarn. By using fabrics made of recycled materials we are helping to reduce landfills while saving the planet's natural resources of crude oil. Recycled polyester The fleece we use in our collection is made from recycled plastic bottles. It’s a material that requires less energy to make than traditional polyester – yet another way to reduce our environmental footprint.
