Onyx Weightlifting Belts – Built for the Platform. Built to Last.

I know the frustration of a belt that’s one hole too loose or one hole too tight.

I’ve felt a belt pinch between my ribs and hips during heavy cleans.

I’ve had my shirt get caught and pulled through the buckle.

And I’ve spent money replacing belts that looked solid at first — but didn’t hold up over time.

Those experiences are exactly why I designed ours.

At Onyx Weightlifting Co., we didn’t just want to make another leather belt. We set out to build the best weightlifting belt for Olympic weightlifters — because we understand two things deeply:

  • Leather craftsmanship

  • How weightlifting equipment should feel under a heavy barbell

When you combine both, you don’t get a generic gym belt.
You get something built specifically for the platform.

Two Core Competition Belts

The Belt (4 Inch)

Our flagship model.

  • 4-inch back support

  • Regulation size for sanctioned meets

  • Tapered to contour along the ribs and hips

  • Available in multiple color options

This is the belt most lifters gravitate toward. It delivers strong lower back support without feeling bulky, and the taper prevents the common rib-to-hip pinching that so many belts cause.

The 3 Inch Belt

Designed for lifters with shorter torsos who struggle with traditional 4-inch belts.

  • 3-inch back width

  • Regulation competition size

  • Same structural integrity as The Belt

  • Available in one focused color option

If you’ve ever felt jammed between your ribs and hips at the bottom of a clean, this belt creates the space you need — without sacrificing support.

A More Supple Option: The Bridle Belt

For athletes who prefer a slightly more flexible feel, we also offer:

The Bridle Belt

  • Made from high-quality Bridle leather

  • Constructed with 2 layers of leather all the way around

  • More supple feel compared to our standard 3-layer-back construction

It still provides excellent support, but breaks in a bit differently and feels smoother against the body. Some lifters love that responsiveness, especially if they prefer a belt that molds quickly while still maintaining structure.

Built Different — Because We Build Them Ourselves

Every Onyx belt is:

  • Handmade in Southern California

  • Constructed with Chicago screws 

  • Hand burnished

  • Built with a 3-layer back and 2-layer front (The Belt & 3 Inch Belt models)

  • Made from vegetable tanned leather designed to age beautifully

The 3-layer back creates rigidity where you need it most — for bracing under heavy squats and cleans. The 2-layer front allows mobility so the belt moves with you instead of fighting you.

Our holes are spaced ¾ inch apart, eliminating the “almost tight enough” problem.

Our roller buckle sits on top of the belt, preventing shirts from getting pulled or torn.

Our low-profile loop keeps the bar from clipping during cleans.

None of these details are accidental. They’re all responses to real problems I experienced myself.

Built for Olympic Weightlifting

Our belts have been worn at the Olympics and World Championships. They’ve been trusted under the heaviest lifts — not because of hype, but because they perform.

When you step on the platform, your belt should feel like part of your setup — not something you’re adjusting between attempts.

That’s why we built ours the way we did.

If you’re looking for a handmade leather weightlifting belt designed specifically for Olympic weightlifting, choose your model, break it in, and feel the difference yourself.
