Additional Product Information


Main fabric

  • 100% Polyester cationic

A high-tech kids' t-shirt made out of plastic bottles

Polyester is made from oil-based chemical derivatives. The CO2 emissions of this material are significant and resources are used up in the production process. It is important to provide a solution to the environmental concerns of sports users through innovation in industrial processes, recycling and the circular economy. That's why we have chosen to make this product out of recycled polyester made from plastic bottles.

New kids' sizes

Based on your feedback, our kids' products are sized too small! That's why, from 2020, Kalenji kids' athletics T-shirts will be sized according to height and age to help you in your choice. They will fit kids measuring between 3'8" ( 5-6 years) and 5'8" (14-15 years). We hope this will better meet your needs!

A score to compare the environmental impact of products

An overall ABCDE score is calculated to help you more readily identify products with the best environmental performance by comparing the same type of product (T-shirts, pants, backpacks etc.). Decathlon is committed to visually displaying environmental information. For more information:
