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.

Designer Notes
-
Dual-Layer Engineering
Two fabrics, two jobs. A 100% organic cotton shell handles the outside, lightweight breathable, built to age well. A 100% merino liner sits next to skin, where it regulates temperature and resists odour. No synthetics, anywhere.
-
Why 17.5 Microns
Merino is measured in microns, the lower the number, the finer the fibre. At 17.5, we're in ultrafine territory: smooth enough next to skin to skip the itch, fine enough to wear back-to-back without the stink.

Built for More
Designed to live beyond the workout. A zip pocket keeps your phone and keys secure on the move, and a 100% cotton drawcord finishes the waistband, no synthetic feel. Wear it to train, then keep it on.
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.
