The AROW Collection is the result of a local supply chain of designers, pattern-makers and seamstresses who produce high-quality garments in working conditions that are a world away from typical sporting apparel manufacturers.

Cut, sewn and finished at Petratex, Portgual - at the very forefront of sports apparel tech globally.

The AROW Baselayer uses Pontetorto®
Tecnostretch—an Italian fabric engineered
for warmth, stretch, and moisture control.
Weighing just 200g, it’s ultra-light, fast-drying,
and packable, with a brushed inner for comfort
and a smooth outer for clean layering.
