0 Polyester Policy

Zero-Polyester policy at BOU.

At BOU, we think the first step to a greener future is awareness and education. We spread this message by informing people with full transparency. We guarantee 100% clarity on every fabric used in our pieces—clearly shown on each product page.

We follow a strict zero-polyester policy—100% no oil-based plastics. We use natural and plant-based fabrics like organic cotton, linen, hemp, and Tencel. This keeps your skin healthy and oceans clean.

How Polyester Is Made (And Why It Can't Be Recycled)

Oil from the ground → chemicals heated → melted into plastic threads → cooled into fabric. Result: 99% ends up in landfills or oceans. Natural fabrics like cotton can be reused forever—polyester gets too weak and dirty. Wikipedia, 2025

Why Polyester Hurts Your Health

Polyester releases chemical particles onto your skin. These irritate, cause rashes, allergies, and mess with hormones like estrogen. It traps sweat, grows bacteria, and smells bad. Cotton or linen breathes better and keeps you fresh. Lefty Production Co., 2026

Oil-based plastics like polyester release chemicals that irritate skin, cause allergies, and mess with hormones. They're linked to higher cancer risk and immune problems from toxins like BPA and PFAS. They also trap sweat (bacteria smell) and shed microplastic fibers when washed (Sustainable Fashion Forum, 2023)

How Polyester Destroys Nature

Washing one load sends 700,000 microplastic fibers to oceans. Over half of sea turtles eat this plastic, thinking it's food. It blocks their guts and raises death risk 22-90%. Polyester takes 200+ years to break down, poisoning wildlife forever. (Nature, 2018 EEA, 2022)
