Race to Zero is an ultralight packable system built for running 5k or 5 days straight. Each piece is built with advanced materials, packs down into itself, and fits into the palm of your hand. Weighing just 127 grams the Race to Zero Shorts are built from densely-woven nylon microfibres that are engineered to be the same thickness as silk.

Water repellent, fast drying and highly elastic, they’re ultra-soft and lightweight, while being durable enough to work in the toughest races. All the seams and details are laser cut and bonded to reduce the chance of chafing. And the inner lining of the shorts is made from the same Italian material as the Race to Zero T Shirt. The lining is engineered with thousands of tiny perforations to create airflow, while a silver-based antimicrobial treatment fights the odour molecules created by sweat. The high visibility Aerospace Orange edition are made with the same high contrast colour as NASA’s Advanced Crew Escape Suits, for the times you definitely want to be seen.
