Description: The firmest, best belt in the world with unmatched buckle strength. Available in one prong zinc plated steel, seamless roller buckle.

  • All Inzer Forever Belts ™ are one solid thickness of the finest, select, exclusive leather. It is not layers glued together cheaply to make thickness as some other brands that can come loose years later. There are no compromises in quality in the Forever Belt ™.
  • Seamless, zinc plated steel roller buckle is unmatched in strength and durability, and it looks great.
  • The buckle prongs do not waver back and forth. They slide one direction into and out the selected prong hole. This makes it easy to place the prong in the hole, saving you time when getting ready to lift.
  • Six rows of lock-stitched, corrosive resistant, hi-density nylon.
  • The edges of the belt are finished with refinement but not rounded. Rounding of the edges lessens the effective width. Therefore the complete competition legal width is maintained in the Forever Belt ™.
  • Finished with top quality, fine suede providing non-slip surface.
    Does not turn soft and fold over as another brand’s belt tends to do. Conforms to your body shape over time and forever stays rigidly supportive.
  • High compression riveted with the same rivets as used in the Space Shuttle program. Not bradded. Will never come loose. 
  • Tongue loop is riveted instead of sewn providing further security. 
  • Closer prong holes for more choice in precise fitting.
  • IPF (International Powerlifting Federation) Approved

Amazing quality

I am beyond impressed with this lifting belt! And the customer service plus super fast delivery were amazing too. The quality of the belt is incredible and honestly I just can’t say enough good things!!

awesome belt needs some working in though

great belt, I personally like prong belts a lot more than lever belts, it is stiff so it will need some working in but I've used this same belt before and once worked in they're a dream super comfortable.

Bangin' Belt

love this belt, really helped me achieve optimal abdominal pressure. I feel like I can lift so much more weight wearing this. Was very pleased with the very rich colour.

13 mm single prong belt

Amazing belt. Sturdy and well built. Can’t wait to get it broken in a bit so I can use it to its full potential! Thank you InnerStrength for your fantastic customer service and great product!!!!

This belt is amazing. Some people seem to say it's ''to stiff'' but if you are a powerlifter the belt is perfectly fine. 13 mm feels great, even better than 10mm. I was between L and M (36''), I ordered M and I have 3-4 hole left so it's perfect.
