What do we all have in common?

The commitment, the will, the determination to have a concrete impact in the sports industry, to invent a new model, and the desire and requirement to create the best running products, for all conditions, for all distances. But also, the passion for running, surpassing oneself, the joy of running and pushing our limits together!

We are a community of enthusiasts, we believe that each stride, each movement, each pulsation can become a step forward for the protection of the environment.


"What a chance to develop Circle Sportswear every day with teams committed and driven by a mission: taking care of yourself and the planet! Circle Sportswear is more than a Brand. It's a Community, a vision. " - Romain Trebuil CEO & founder of Circle Sportswear




Circle is a collective of enthusiasts, an ecosystem of experts who share the desire to surpass themselves to innovate even more. The collective is the Circle team, our partners, our ambassadors and athletes. It is together that we test the performance and technicality of each product and it is together that we succeed in finding solutions to get around the obstacles.


Circle offers its employees an agile work environment adapted to each person's performance and life. We are convinced that the success of the company depends on the development of its teams and we therefore make it a point of honor to offer them a pleasant and stimulating environment. It is in the heart of La Caserne, in Paris, where we operate in a creative and pioneering environment in sustainable fashion. Running is a shared or emerging passion for every Circle employee. We seek to promote well-being and sport and we regularly share racing weekends to live our common passion and meet our community.


We apply the same transparency with our clients as internally on the evolution of our projects. With our customers, we share our developments and future projects and share all manufacturing information to allow everyone to understand the number of stakeholders to develop and manufacture our products. Internally, we ensure that we adopt a management and internal communication method that is as transparent as possible. We do not have a traditional view of hierarchy and all voices are heard when it comes to making a key decision. Information must flow freely to enable the team to function properly and ensure fluid communication.


At Circle, sports practice is at the heart of our values. We offer and encourage each employee to practice and attend running classes accessible free of charge every week in our premises as well as advantageous rates to register for numerous sports classes in Paris.


Because our values ​​are strong and our environmental and social objectives ambitious, we are continually seeking excellence. We ensure that we always guide our choices in order to honor our commitments, in terms of quality, material sourcing and even strategy. We encourage all members of the Circle team to question their habits and to continually question processes that are anchored in their way of operating. We are convinced that it is always possible to do better and want to encourage them to demonstrate adaptability, creativity and anticipation when faced with the innovations and ideas that present themselves to them.



It is crucial that as pioneers, we continue to find innovative business models... as this would mark the start of a new era for strong and innovative partnerships.


Because they are the guarantors of the sustainability of our approach, we decide to surround ourselves with partners who share the same vision of ethics and development as us. For our part, we are committed to remunerating our partners at the right price, that is to say the price which allows employees to earn a decent living, which ensures the sustainability of the company and which guarantees a fair redistribution of capital. This price must correspond to the level of quality that we demand and it must allow partners to develop over the long term with us.

We require our partners to comply with our Code of Ethics. The latter takes up the main principles of workers' rights and is based on fundamental European laws. Furthermore, our strong attention to the traceability of our products requires us to know all of our partners well. We meet our manufacturing partners to find out directly about the working conditions. In addition, as our partners are located in Europe, they must all respect European fundamental rights. This is particularly why we want to keep our partners close to us so that they are governed by these laws. Finally, Circle teams must respect the integrity of partners and communicate with them with respect and kindness.


We have developed with all our partners a method of communication based on honesty and transparency. We take an equal stance and reason with them as extensions of the brand. We always keep them informed of important progress at Circle: new recruitments, fundraising, important decision-making choices and developments in our CSR policy. In return, we expect our partners to also be transparent and to communicate to us all important information that could have an impact on us.

Some of them have been with us since the beginning and are at the heart of our ecosystem. We have developed great trust in our partners, and are convinced that collaborating with them will have a positive impact for all stakeholders.


We expect our partners to be driven by the same values ​​as us and thus wish to create a true ecosystem of committed partners. We wish to collaborate with partners concerned about the environment, sustainability and the after-life of the industrial process, focused on an industry of the future and innovative in their eco-responsible approach. We encourage them to share all their innovation and sustainability projects so that we are aware of their progress and can take advantage of it to evolve with them in a truly sustainable approach.


In collaboration with numerous race organizers such as the organizing committee of the Tours Marathon and the 10 KM Paris Tour Eiffel, we are proud to lead an initiative aimed at raising awareness and engaging all stakeholders in the world of sport in a more responsible era. We now offer runners the opportunity to opt for a durable and eco-responsible t-shirt, made in Europe from 100% recycled plastic bottles. This responsible alternative aims to replace the traditional t-shirts given to participants upon arrival, which are generally produced abroad from petroleum-based materials, are not recyclable, and often end up quickly abandoned or relegated to the bottom of the bin. our closets.
