Soar Men's Protolab ADV Marathon Shorts "Black"

Founded in Hackney, London, SOAR Running continues to push race-day construction inside ProtoLab. The ADV Marathon Short removes the traditional waistband entirely, replacing it with a one-piece integrated waist and pocket system that sits flatter against the body — reducing pressure, limiting movement and enhancing comfort at pace.

Designed to disappear once worn, the short remains stable over distance. Storage is engineered directly into the structure: a rear pocket carries up to four gels, two dedicated loops provide additional fuelling access, and a zipped pocket secures a phone without bounce. Everything is positioned close to the body - quiet, controlled, race-ready.

The outer is cut from SOAR’s lightest-ever French woven fabric for maximum airflow and minimal weight. Laser-cut hems and bonded seams reduce friction, while reinforced side splits maintain stride freedom without compromising structure under load.

A refined marathon platform where comfort, carry and speed operate as one system.
