5 reasons to ditch toxic polyester

P.S You'll never go back

1. Your Skin Eats What You Wear

Your skin isn’t a barrier, it’s a sponge. When you sweat, your pores open up, and polyester leaks chemicals straight into your body. Just like a moisturizer, but loaded with toxins.

2. It Was Never Meant for Humans

Polyester is melted plastic bottles and petroleum byproducts. It was never made for skin, it was made for profit.

3. You’re Absorbing Chemicals You Can’t Pronounce

From softeners to dyes, synthetic fabrics are soaked in toxins. These don’t stay on the surface, they’re absorbed into your bloodstream, especially during sweaty workouts.

4. It Gets Worse When You Sweat

Heat and movement speed up the leaching process. The image below shows how quickly different body parts absorb things through the skin, with some areas soaking up much more than others.

5. The Plastic Ends Up Inside You

Polyester sheds microplastics into the air, your lungs, your blood. They’ve been found in sperm, breast milk, and unborn babies. Once they’re in, they don’t come out.

Switch to all natural

We’ve eliminated polyester entirely. Nero shorts combine premium Merino wool and organic cotton designed for breathability, odor resistance, and unmatched comfort.
