What Makes Activewear Sustainable & Ethical?

Most of the mainstream activewear is made from fabrics such as polyester, nylon, and lycra. Such materials contain plastics and cause so much damage to the environment. When you wash such sportswear, tiny micro-plastics can break off and end up in our oceans affecting marine life.

According to statistics, the textile industry produces synthetic chemicals and dyes that cause almost 20% of industrial water pollution. Additionally, so much water goes to waste while producing clothes. For instance, 2.6% of our global water is used to produce cotton alone.

Sustainable clothing on the other hand causes minimal impact on the environment. Sustainable activewear is manufactured, marketed, and used in the most sustainable manner possible.

Brands that make sustainable activewear use recycled plastic ensuring many single-use plastics don’t end up in the already overflowing landfills. Others use natural, biodegradable materials such as cotton and bamboo which come from renewable sources and have a low environmental impact.

Sustainable activewear is produced through careful and efficient use of natural resources such as water, land, and soil. Some brands go even further and use renewable energy sources.

Sustainable activewear brands also ensure they adhere to proper working conditions in the field, factories, transportation, and stores.
