Do you REALLY think wrapping yourself in plastic is good for your skin?

1. Polyester is literally plastic - against your most absorbent skin

Those "performance shorts"? Just plastic in disguise. Often the same type of plastic that water bottles are made of - shedding microplastics onto your skin with every workout.

The skin between your legs is one of the most absorbent surfaces on your body. Does that sound like something you want plastic on?

2. Polyester Traps Heat - the #1 cause of heat rash

Heat rash and prickly heat happen when sweat ducts get blocked. Polyester does exactly that: traps heat against your skin, plugs the ducts, and creates the perfect conditions for irritation.

That clammy, hot, "I need to peel these off" feeling? That's your polyester shorts.

3. CHEMICAL FINISHES + BPA/PFAS ABSORB DIRECTLY THROUGH YOUR SKIN

Your "moisture wicking" shorts? Coated in chemical finishes - and often toxins like "forever chemicals".

Research shows these chemicals can leach via skin contact. Does that sound good for your skin?

4. Polyester breeds bacteria - causing sweat and stink

When you trap heat & sweat against your skin, bacteria thrive. And synthetic polyester is the perfect breeding ground.

The same bacteria that cause jock itch, butt acne, and make you smelly down there. Not exactly what you want from your workout gear.

5. Polyester can trigger DERMATITIS - red itchy skin

If you’ve dealt with chafing or bright red irritation, your shorts may be part of the problem.

When sweat and heat stay trapped, irritation and chafing become more likely — especially during movement.
