The Leather Working Group (LWG) is an international non-profit organization composed of stakeholders in the leather product supply chain. The organization has developed an audit program that is committed to promoting environmental best practices throughout the supply chain of the leather and related industries.

Since 2022, we source 100% of our leather from LWG-certified leather manufacturers. They have all achieved a silver medal in the LWG audit. This means that the amount of resources used has been significantly reduced and recycled where possible (energy, water, materials and chemicals). Wastewater is purified and the storage of materials is subject to strict rules. Working conditions have also improved.

We are currently investigating leathers that offer a high-quality sustainable alternative to the current standard. We always remain open to alternatives. Would you like to know more about our sustainable vision?

The Forest Stewardship Council (FSC) is an organization committed to promoting responsible management of the world's forests according to strict environmental, social and economic standards.

The certification guarantees that forests are managed in a way that preserves the biological diversity in holds. In addition, forestry according to FSC standards benefits the lives of local people and workers, while ensuring economic viability. This enables companies and consumers to choose wood, paper and other forest products that are made from materials that support responsible forest management.

All our cards on and in the bags come from FSC-certified suppliers. This also applies to the boxes in which we send the Pylos59 bags to our happy recipients.


We want to reduce the use of raw materials. By collaborating with Waste2Wear, our bags are provided with a recycled lining. Waste2Wear makes textiles from recycled PET bottles (rPET). Are you curious about how this production process works? Then watch the video below:


All Waste2Wear fabrics can be shown by means of an RA3 test to be 100% rPET material. And not a combination of 'virgin' material. A product with a much lower percentage of rPET can also be designated as recycled material, but we do not participate in that. We choose Waste2Wear because we value the fully traceable and transparent supply chain, with the guarantee of fully recycled material.

Waste2Wear won the World Sustainability Award in 2021 in the Supply Chain category. We are proud of that.


To keep our footprint as small as possible, we reinforce shoulder straps with recycled cotton. The production of new cotton involves the use of a lot of water and pesticides. So recycled cotton is a sustainable choice, in line with our mission. This cotton meets the requirements of the Global Recycled Standard (GRS).


When you open the box to view your Pylos59 bag, you may notice that it has a plastic bag around it. This is not just any plastic, but made from 100% recycled material or recyclable material. We aim to use only fully recycled polybags in 2024. These 'polybags' prevent your new bag from being damaged during transport.

In addition, we do not use silica granules, but instead use a biodegradable product, made from special clay granules. You will find this in small packages in our bags, to prevent any moisture build-up during transport. This way we guarantee the quality of our bags during transport.
