How to Be a Savvy Sustainable Shopper
As you explore these brands, remember that the most sustainable item is the one you already own. When you do need to buy new, look for these markers of a truly responsible brand:
-
Certifications: Look for B Corp, Fair Trade, GOTS, and OEKO-TEX.
-
Material Transparency: Brands should be clear about what their fabrics are made from (e.g., recycled polyester, organic cotton).
-
Circular Initiatives: Support brands that offer repair, resale, or recycling programs for their products.
By choosing sustainable activewear, you're not just investing in your fitness; you're investing in a healthier planet. Your power is in your purchase—use it to support companies that are stretching towards a better future.
