Technical information

A technical kids' T-shirt made from plastic bottles

Polyester is a synthetic fibre made from petroleum. This material has a significant carbon impact and its manufacture depletes our natural resources. It's important to respond to athletes' environmental concerns by carefully choosing our industrial processes, by recycling, and by investing in the circular economy. That's why we've chosen to make this product from recycled polyester obtained from plastic bottles.
