Sizing Chart - Running Short - 2026

Fit Guide

These running shorts have a relaxed fit with a short leg and high side split for freedom of movement. The waist is elasticated with an adjustable drawstring for comfort.

Between Sizes?

Go by your waist. For the most comfortable, relaxed fit we'd suggest sizing up — the elastic sits softer and the drawstring pulls in any excess, so it stays put.
