Polyester - Polyethylene terephthalate or PET for short, synthesized from fossil fuels or organic sources.
Its production emits toxins into both air and waterways.
Polyester fabric releases toxic gas phthalates into the air and through contact with the skin. Exposure to phthalates can disrupt normal ovarian function by several different mechanisms, leading to reproductive and non-reproductive abnormalities.

Once in the environment, it takes about 20 years to degrade. It's a known hazard for aquatic animals.
