Plastic Polyester Leaches Toxins
Synthetic activewear traps heat and moisture against your skin. Polyester and other plastics don't breathe and can leach harmful chemicals into you skin when you sweat.
Sheds Microplastics
Every time you wear polyester, millions of microplastics shed onto your skin and into the air around you.Do you really want that on your skin?
Full of Toxic Chemicals
Traditional activewear contains formaldehyde, BPA, and synthetic dyes that absorb directly through your skin — your body's largest organ.
Disrupts Hormones
Studies link polyester's endocrine-disrupting chemicals to hormonal imbalance and skin irritation.What's on your body is in your body.
