OpéraSPORT has developed a preferred material list to assess the environmental impact of the materials we work with. We took existing benchmarks such as the MADE-BY Environmental Benchmark and the Higg Materials Sustainability Index as a starting point. The fibers are evaluated based on their CO2 emissions, human toxicity, eco-toxicity, energy consumption, water consumption and land use. 

Materials that are ranked as “recommended” or “good” are considered to be more sustainable. Materials in the category “discouraged” we want to replace or find more sustainable options for. Materials that are “banned” are for animal welfare reasons. Materials that are “unclassified” are unknown for their environmental impact and are hard to assess. The Preferred Material List is used as a guide for our designers and fabric sourcers. Here at OpéraSPORT, we want to encourage them to pick the best options available, with preference for the “recommended” materials. We strive to only work with materials in the recommended category. Unfortunately, due to consideration for durability, sometimes a small percentage of spandex or elastane has to be blended into recycled fabrics. 

All fabrics used by OpéraSPORT must comply with one of the below criteria: 

• Organic and GOTs Certified Material 
• Recycled content
