ECOVERO™ Viscose is a fiber developed by Lenzing from wood sourced from sustainably managed forests. This fabric is particularly popular for creating flowing and printed pieces in Hartford’s women’s collections. Certified by the European Ecolabel, it stands out for its reduced environmental impact throughout its production cycle. Compared to traditional Viscose, ECOVERO™ generates up to 50% less CO₂ emissions and water consumption. The traceability of raw materials is ensured, allowing for the precise identification of the origin of the wood used.

The BCI (Better Cotton Initiative) label aims to improve cotton farming practices worldwide. It promotes more responsible farming methods, reducing the use of water, pesticides, and chemical fertilizers, while preserving soil health and ecosystems. BCI also supports cotton farmers by improving their working conditions and promoting agriculture that is more resilient to climate challenges.

The EUROPEAN FLAX™ label certifies linen grown in Western Europe using environmentally friendly farming practices. It is this fiber that we prefer for the production of our men's linen shirts. Linen is naturally eco-friendly: it requires little water, no GMOs, and very few chemical inputs. Since every part of the linen plant is used, it generates virtually no waste. The certification also ensures full traceability of the fiber, from cultivation through to spinning.

The FSC® label guarantees that fabrics, such as Viscose or Modal, come from responsibly managed forests.

The GOTS (Global Organic Textile Standard) label is the global benchmark for organic textiles. It guarantees that at least 70% of the fibers used in certified Hartford garments are sourced from organic farming, free from GMOs and chemical pesticides.

The GRS (Global Recycled Standard) certifies the use of recycled fabrics while ensuring traceability, transparency, and compliance with strict environmental and social criteria. It applies to the entire production chain, from the collection of raw materials to the finished product.
