Our Materials
Why all of this? By deliberately using natural materials like cork and organic cotton, we strive to promote not only style but also environmental sustainability. Join us and explore the world of sustainable alternatives together to understand how each of your purchases contributes to preserving our precious resources.
Microplastics: A Threat to a Clean Environment and Water Quality
In a world where a clean environment and water quality cannot be taken for granted, the issue of microplastics is coming increasingly into focus. These tiny plastic particles pose a significant threat to our ecosystems and our health. The use of natural materials offers a sustainable alternative to protect our environment and ensure clean water for future generations.
Clean Air: The Challenge of Non-Biodegradable Materials
Clean air is not something we can take for granted, and the impact of non-biodegradable materials on our air quality is alarming. However, consumers can make a significant difference by consciously choosing products that are manufactured in an environmentally friendly way and are recyclable. By rethinking our purchasing decisions, we can actively contribute to preserving clean air and reducing pollution from non-biodegradable materials.
Cork
Cork is the all-rounder among sustainable materials—we love cork. The first products we launched are made of cork, and for good reason. Cork is harvested from the bark of the cork oak tree, with the first harvest taking place at around 25 years of age and subsequent harvests every 9 years. A single cork oak tree can produce up to 1,000 kg of cork, and the tree can live for up to 250 years. A stripped cork oak tree binds up to four times more carbon dioxide, making it beneficial for both people and nature. No trees need to be cut down for this purpose; the use of cork thus actively contributes to climate protection and results in an all-around positive ecological footprint. What should you look for? We manufacture our cork products in Portugal, which conserves resources and avoids long transport routes.

Our activewear is made from TENCEL™ because the material not only feels great to wear but also sets the standard for environmental sustainability. TENCEL™ is derived from wood, primarily eucalyptus, sourced from sustainably managed forests. Production takes place in a closed-loop system in which up to 99% of the solvents used are recovered and reused—a true pioneer in the circular economy. TENCEL™ is biodegradable, requires significantly less water to grow than cotton, and does not require pesticides. This makes the fiber particularly eco-friendly and gentle on the skin. Our TENCEL™ fabrics are processed in Portugal—ensuring the highest quality, fair working conditions, and short supply chains.

ROICA™ V550
ROICA™ V550 is an innovative stretch fiber that combines exceptional comfort with sustainable technology. Unlike conventional spandex, which takes several hundred years to decompose, ROICA™ V550 is fully biodegradable and Cradle to Cradle® Gold certified. For us, this is crucial—because persistent pollutants in nature are a no-go. The fiber is designed so that it can be returned to biological cycles after use. ROICA™ V550 thus enables truly circular textile production—an important step toward genuine sustainability. Our fabrics are processed in Portugal—fairly, with high quality, and with short supply chains.

Wood is a highly sensible alternative to plastic products. But it makes little sense to transport tons of wood in containers on huge cargo ships all around the globe. For example, when we state on our balance boards that the wood comes from FSC-certified sources in Europe, this makes a significant difference. FSC certification stands for biodiversity, the expansion of natural forests, and the sustainable management of forest resources.

Cotton
Cotton is a natural product that is biodegradable. We use only organic cotton, with no added polyester or other synthetic materials. Our products are also certified under the Global Organic Textile Standard (GOTS), which covers not only the cotton but the entire production process, from cultivation to packaging and beyond.

We love not only natural materials, but also clear communication. Most products made from natural rubber are nothing more than greenwashing! These are sourced from Asia at rock-bottom prices, marketed as natural rubber with unspecified additives, and touted as “natural”—yet the cultivation process is never scrutinized. Hardly any producer can say what additives are contained in the natural rubber. But there are also positive initiatives. As with wood, there is FSC certification for natural rubber. However, many companies skip this step and do not scrutinize their supply chains. As with wood, paper, and other FSC-certified products, manufacturers and consumers can use these products knowing that the rubber was produced in forests or plantations with safe working conditions and good relations with local communities, without deforestation or other environmental damage.

Recycled plastics
There is a wide range of practices here, extending all the way to blatant greenwashing. In the yoga sector, for example, recycled materials (from Asia) are marketed as sustainable. These materials are reprocessed using chemicals and transported in massive cargo ships—that cannot be the right approach for us. That is why we need to take a closer look. Why is a fundamentally environmentally harmful material described as sustainable simply because it is recycled and reused? Wouldn’t it be better to do without it altogether? After all, the problem of plastic waste and microplastics—which also wash up on European beaches—remains. In our view, there is at most a benefit if a recycled material is mixed with natural materials, thereby increasing the product’s utility and ensuring the overall material is durable.
