The demand and need for brands to get involved and bet on a more circular economy is increasing.

At Arena Martínez we are committed to turning towards a more conscious production and communication in fashion, being responsible for the social and environmental impact. We develop our Supply Chain consciously, prioritizing a more circular economy with the optimization of each process, lengthening the life cycle of each piece and promoting awareness and respect for the environment.


We develop capsule collections, with very limited units, prioritizing quality, uniqueness and awareness when creating each piece.

The use of natural fiber textiles such as recycled cotton poplin or synthetics exclusively made from recycled polyester and also using organic Florence Twill.

Collection packaging: bags made from recycled cotton.

For our next collection we are incorporating technical systems and sustainable materials in order to minimize the impact of our productions.

  • Biomaterials: We are currently investigating and implementing the production and use of biomaterials that are environmentally friendly in both their production and life cycle.
  • Digitization: both pattern development and prototyping are being done digitally in CLO3D, which recognizes not only an innovation in the production process but also a more sustainable alternative.
  • Natural pigments: The dyeing process is being carried out by using natural pigments, an ecological alternative less polluting for our environment.
