You swapped out non-stick pans, cut out seed oils, and refuse to microwave food in plastic. Yet, during training, when your body temperature spikes and your pores dilate, you are wrapping your skin in petroleum-derived plastic

2. The Hormone Trap
A published clinical study showed that men who wore polyester against their groin suffered crushed sperm counts, poor motility, and measurably smaller testicles due to synthetic heat traps and electrostatic friction. Stop letting cheap melted crude oil cook your hormones while you train.

4. Big Activewear loves 95% product margins
Over 90% of gym wear uses polyester because extruded crude oil costs pennies at scale. Traditional brands charge $80 for cheap plastics wrapped in loud logos.
Nero takes the margin hit to build uncompromised activewear using New Zealand RWS-Certified Merino Wool and certified organic cotton.
