There is an increasing demand and a need for brands to get involved and bet on a more circular economy. At Arena Martínez we are committed to turning towards more conscious production and communication in the fashion sector, being responsible for the social and environmental impact. We develop our conscious Supply Chain, 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 of very limited handmade units, prioritizing quality, uniqueness and awareness when creating each piece.

We bet on more sustainable distribution alternatives when working with the courier company TIPSA.

They are also a reference partner in the fight against Covid-19 for admirable social action



We try to keep materials in the cycle as long as possible, minimizing waste and extending the life of the product:

-Creation of capsule collections from leftover remnants

-Reuse of pieces to create new parade clothes, hand-painted by artists for example.

-Reuse of scraps as visual elements on the display of our events (eg. Scraps used to create a structure simulating a flower garden with our prints)

-Collaboration with manufacturers from the Preciados Gallery to create this collection from thousands of threads and accessories that were to be discarded.

-Transfer of surplus materials and remnants to artists to develop their works.

-We adjust the remaining stock with discounts to give it an outlet, avoiding burning your pieces under any circumstances.

-We offer product repair to facilitate lengthening the use of customers
