The Birth of ONX

Wittman’s obsession with performance gear didn’t start in a boardroom.
It started on the mat.

He saw fighters breaking bones in gloves that weren’t built for real training. Wrists giving out from lack of support. Athletes losing valuable time to injuries that better equipment could’ve helped prevent.

So he built something better.

ONX was engineered with one mission:

To redefine protection and performance for elite fighters.

Because when you’re chasing greatness, your gear should keep up.

ONX gloves and equipment are designed from the inside out—with smarter fit, superior support, and the insights of a coach who’s been there, done that, and cornered the world’s best.

  • Better support means fewer breakdowns.

  • Higher-performing gear means higher-performing athletes.

  • It’s that simple.

This isn’t a company that licenses a name.
This is a movement, designed in Wittman’s own lab—crafted, tested, and refined with the same precision he brings to every corner.

Fight IQ Meets Innovation

Trevor’s also a respected voice in the boxing world, having worked with elite pros like:

  • 🥊 Manuel Perez
  • 🥊 Verno Phillips
  • 🥊 Juan Carlos Candelo
  • 🥊 DeAndrey Abron
  • 🥊 DaVarryl Williamson

His unique ability to blend boxing precision with MMA complexity is part of what makes his fighters—and his gear—so effective.
