Sustainability

Sustainability isn't a destination—it's a continuous journey.

At Cosiol, we know that no brand is perfect. Instead of making unrealistic promises, we focus on making thoughtful choices every step of the way.

European Linen

Linen is one of the world's oldest and most durable natural fibres.

Whenever possible, we work with premium European linen sourced from suppliers holding the European Flax® certification. This certification guarantees that the flax is grown in Europe without irrigation, without genetically modified organisms (GMOs), and with full traceability throughout the supply chain.

Linen is naturally breathable, exceptionally durable and becomes softer with every wear, making it a material designed to last for years rather than seasons.

Certified Fabrics

Many of the fabrics used by our suppliers are certified according to OEKO-TEX® STANDARD 100, ensuring they have been tested for hundreds of harmful substances and are safe for direct contact with the skin.

Whenever available, we prioritise certified materials that meet recognised environmental and safety standards.

Natural & Innovative Materials

Alongside linen and cotton, some of our collections feature Piñatex®—an innovative plant-based material made from pineapple leaf fibres, an agricultural by-product that requires no additional land, irrigation or pesticides.

Piñatex® offers a durable, vegan alternative to traditional leather while giving new purpose to existing natural resources.

Thoughtful Packaging

Every order is packed using recyclable paper packaging produced in Poland.

Our shipping materials are made from FSC®-certified paper, supporting responsibly managed forests and ensuring our packaging can be recycled after use.
