Description:  Forever Belt quality in the 10mm choice. Available in one or two prong precision buckle.  All in stock belts are single prong unless otherwise noted.

  • minimum of 10mm conforms to your body shape sooner and is considered by some to be more comfortable. 10 mm thickness is also a choice for lifting applications when a thicker belt is not needed. 
  • 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 ™.
  • Precision, custom, 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.
  • Four 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 overly soft and fold over as another brand’s belt tends to do.
  • Conforms to your body shape over time and forever stays firmly 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.

Love this belt!

Leather breaks in much quicker than i anticipated. Absolutely stunning belt! Ordered the wrong size but easy to return and get the correct one. Inner Strength is an amazing company to deal with! Very happy with my purchase!

High quality

i loved this belt! Very solid thickness, the leather is very high quality and the color is great. My lifts have improved because the support I get from this belt is great. It takes a wgile to break in, as it is very stiff at first, but after a few uses it worked really great. A great first belt for me, thank you!

The first day squatting with this belt was tough. It was very stiff and left bruises around my ribcage and hipbone. However, after a couple days of breaking it in via rolling and wearing it around the house, the belt feels great.

inzer single prong

extremely stiff out of the box, broke it in by rolling it up tightly and compressing it under a heavy object. Left it for a few hours, rolled it the other way etc. did this for a few days and it broke it quite nicely. I’ve worn 3 times so far and it bruised me up pretty bad, but I feel it forming to my body with every session. In a little while it will be completely broken in and I will have a high quality belt that lasts for years and years. Great product.

Good Belt

I had a rogue 4" belt prior to this that was just fine. I bought this one because I needed something IPF approved. Its pretty stiff, but i prefer it that way. Would definitely recommend. They fit on the larger side, so make sure you read sizing information carefully. I ordered the wrong size, exchange was very easy and fast.
