Built to grind. Built to win.

The FLX Pro Short isn’t for flash. It’s for function. Designed to take a beating and come back for more — every squat, sprint, and sandbag rep. No gimmicks. No flair. Just gear that does its job so you can do yours.

Key Features:

  • Scalloped thigh cut for unrestricted movement under load

  • Perforated rear panel to dump heat under pressure

  • Dual side pockets + zippered stash pocket in back

  • Subtle CHLKDUP 3C mark on right thigh — earned, not flaunted

  • Worn in comp floors. Built for the trenches.

Stop chasing hype. Start showing up.

This short doesn’t quit. Neither should you.
