We chose to work with leather because it's a natural material known for its strength and durability. At nat & nin, raw materials represent 40% of its carbon footprint.

Our leathers come from waste from the food industry, which would otherwise be destroyed during the tanning process.

These quality raw materials are selected from recognized and controlled tanneries to guarantee manufacturing carried out with respect for the environment and health.

The leathers are tanned according to the laws in force in the European community, in accordance with the REACH regulation (Registration, Evaluation, Authorization & Restriction of Chemicals) which limits the use of products harmful to the environment and health.

Most of our partner tanneries are LWG (Leather Working Group) certified, a guarantee of sustainability and energy-responsible production. LWG is a protocol that certifies the tanning process in terms of energy and water use, waste management, and the use of chemicals previously adopted in the tanning processes.
