Shorts Size Guide

Just Gains shorts are built with a unisex, relaxed fit for full range of motion — through squats, sprints, and everything between. Use the guide below to find your size. 1-3 cm sizing differences may occur.

General fit guidance

  • If you're leaner or prefer a closer fit, size true to your regular waist size.
  • If you carry more muscle mass — especially through the quads and glutes — size up one from your usual for a more comfortable fit through the leg and seat.
  • All shorts feature an adjustable drawstring waist, so you have some flexibility within a size either way.

By product

Worldwide Mesh Shorts — loose mid-waist cut, drawstring closure, built for full range of motion on every set or sprint. Runs relaxed — if between sizes, size down for a snugger fit or size up for more room to move.

Washed Shorts — White Print — built for leg day, light and sturdy under a loaded bar. True to size for most builds; size up if you prefer extra room through the leg.
