Sustainable clothing brands manufacture apparel using environmentally-friendly materials that reduce the environmental impact of clothing production.
Many companies are also ethically committed to providing fair wages and creating a healthy, safe working environment.
Some people opt for sustainable activewear because they want to have a positive impact on the environment and workers along the supply chain. They enjoy learning where their garments come from and about the production process.
Customers also appreciate timeless pieces that hold up to frequent wear, rather than chasing ever-changing fashion trends. What’s more, people enjoy the uniqueness that small-batch clothing brands provide.
