While the brand does not mention the location or names of the suppliers or production, they mention that their top 100 suppliers make up 80% of everything they buy according to turnover. Their website states that they are part of Amfori BSCI (although they are hard to find on the Amfori BSCI members’ list), Business Social Compliance Initiative, with which they focus on these top 100 suppliers, out of which their top 25 are required to have BSCI audits conducted.
The rest of the suppliers are audited based on a set of steps, between each of which they conduct training to enable progress towards the next one. As of 2020, Gestuz had set targets for health and safety programmes and increasing CSR know-how at all levels, however whether these were achieved is not stated on the website.
They have also signed a Modern Slavey Statement to ensure no modern slavery, child labour, or human trafficking takes place within their supply chain. They have internally created a set of restrictions on chemicals that ensures reduced harm on the workers, as well as the wearers of the garments.
