OptiiForce ForceLock™ Belt
Built to last,
even in the heaviest use
Meet the OptiiForce ForceLock™ Belt. Engineered to hold up under your most brutal sessions, it delivers rock-solid back support and core stability rep after rep — so reliability is the last thing on your mind when you step up to the bar.
Built for Heavy Sets
Every ForceLock™ Belt is cut from full grain leather and built to give you a solid, even brace on squats, deadlifts and presses. With time and use, the leather breaks in and shapes to you.
Top-Tier Full Grain Leather
Each belt is cut from authentic full grain leather with its natural texture and the hide's real markings left untouched — no sanding, no buffing. Expect one-of-a-kind grain, subtle scars, and patterns that prove it's the real thing. What looks like "imperfection" is the signature of superior strength and longevity — a world away from split leather and synthetic imitations.
Heavy Duty Nylon Stitching
The ForceLock™ Belt is reinforced with heavy-duty bonded nylon stitching — a strong synthetic thread with a higher strength-to-size ratio than polyester. It shrugs off moisture, mildew, and abrasion, and resists most acids, alkalis, oils, and chemicals.
Resistant to Corrosion & Stress
Murdered out with matte-black steel hardware that resists corrosion and withstands tensile stress of up to 0 PSI. Locked in, it stays locked in.
Precision-Spaced Holes, Optimal Support
Cinch it tight with minimal effort. The ForceLock™ Belt features precision-spaced holes that let you dial in a custom, secure fit every set — maximum tension, maximum comfort, zero slipping.

Care
- Wipe the leather clean with a damp soft or microfiber cloth.

Note: Use leather soap and similar cleaners sparingly, only when needed. Never dry with a heater or blow dryer — it can fade or damage the leather. Keep out of direct sunlight to prevent the color from fading.
