Your Order Supports Farmers
Your Order Supports Farmers
Nero stands with farmers. While the big sportswear giants fuel plastic factories, we choose to work with those who raise sheep, grow cotton, and keep real fabrics alive.
Every order is a step toward a future where natural wins over synthetic, and where farmers, not oil companies, get supported.

About Our Wool
The wool comes from flocks raised to the highest welfare and land standards in the world, on farms certified by RWS and ZQ. Every fibre is traceable, from the pasture it grew on to the garment you wear.
Woolmark certified, which guarantees fibre content, performance, colour fastness, and dimensional stability at the highest level the industry recognises.
Spun in ultra-fine qualities between 15.5 and 18.5 microns, finer than human hair, and among the rarest merino commercially available.
Engineered and tested to withstand the demands of training, travel, and continual wear. Built to soften, not wear out.
Produced in mills held to Made in Green OEKO-TEX and WRAP standards, environmentally sound, socially responsible, and free from harmful substances.
