Sustainability is an integral part of our business, every single day.

We believe that the future success of our business dependents on bringing sustainable practices into all elements of our operations. Our mission is to be a sustainable lifestyle brand through how we create our product, manage our operations and connect with our community.

BSCI Membership

We are member of the Business Social Compliance Initiative (BSCI)

The BSCI Code of Conduct aims at setting out the values and principles that BSCI participants strive to implement in their supply chains. Each BSCI participant endorses the Code of Conduct as well as the Terms of Implementation, the Glossary and the Reference when joining the initiative.

The BSCI Code draws on important international labour standards protecting workers’ rights such as International Labour Organization (ILO) conventions, declarations of the United Nations (UN) as well as guidelines of the Organization for Economic Co-operation and Development (OECD). It sets out 11 core labour rights, which we as SINNER and our suppliers commit to monitor within our supply chains in a step-by-step development approach.


Our ocean takes care of us. Let's return the favour.

Plastic pollution is one of the greatest threats to ocean health worldwide. By 2050, our oceans will contain more plastic than fish by weight. With buying a pair of our selected SINNER flip-flops, you actively support the work of the Plastic Soup Foundation.

SINNER X Shades of Love

SINNER supports the Himalayan and Andean eyewear project

The most remote communities are the ones that are in the greatest need.

Up in the Himalaya and Andes, at an altitude of 2,500 to 5,000 meters, people are exposed to intense sunlight.

About 80% of the population suffers from eye damage and serious eye diseases. SINNER & Shades Of Love collect sunglasses and distribute them directly among the world’s highest summits and villages.

SINNER X Mission Live

Dance from the deep

This October, Dutch Top DJ and producer Oliver Heldens will make a spectacular free dive. At the bottom of his free dive, Oliver will enter an underwater studio to stage the ‘Dance from the Deep', a unique underwater dance event to save the world's oceans.

With this unique underwater performance, Heldens supports Mission Live Ocean, an initiative founded to raise awareness for the issue of Plastic Soup and to reduce damage done to the environment globally.

SINNER is a proud partner and supports this project in order to generate as much worldwide awareness as possible.
