You’re putting in the work, fuelling your body, lifting with purpose, but shouldn’t your activewear be doing its part too? With skin-contact time running high, toxic dyes, synthetic fabrics, and microplastic shedding shouldn’t be a part of the equation. Here's your go-to list of non-toxic, conscious activewear brands made for women who train smart and live cleaner.
Why Choose Non-Toxic Activewear
When you’re breaking a sweat, your pores open up and your skin becomes more receptive to whatever it comes in contact with. Most conventional activewear is made with synthetic fibres like polyester and nylon. These fabrics are often treated with chemical dyes, finishes, and antibacterial agents. While these help with performance features like stretch and sweat-wicking, they may also expose you to toxins like phthalates and formaldehyde, many of which have been linked to hormonal imbalances and skin irritation. For the StrongHER woman, that should be an absolute no-go.

What to Look for in Non-Toxic Activewear
OEKO-TEX® or GOTS Certifications: This will indicate that fabrics are tested and free from harmful substances.
Plant-Based or Recycled Fibres: Fabrics like organic cotton, bamboo, hemp, or recycled nylon made without toxic dyes or finishes.
No Toxic Dyes or PFAS: PFAS (Per- and Polyfluoroalkyl Substances) are used to make a garment water resistant. These tend to accumulate in your body and environment, affecting the reproductive system and immune system.
Fair Trade & Transparent Production: Choose brands that care about the planet also tend to care about their people.
