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.

Great 1st belt

Purchased my 1st inzer belt. Great quality of product. It's a real stiff one but it takes a while to break in. After a few times, it gets better to put it on. Overall it's a great product.

Great belt at a very

Great belt at a very reasonable and afford price, very stiff, you will need spend some time to get the belt broken in. I think it is the best alternative option if you are looking to buy SBD belt, but have very tight budget at this moment. Don’t waist your money on any other cheaper belts, they are not supportive. Get this belt first, and working hard toward the SBD belt in the next few years.

Great Belt

This is my second Inzer belt. It takes a bit to break in but what else would you expect from a 13mm belt, it's supposed to be stiff! Great belt!

Solid belt, not for me

I had to purchase this belt as the belt I have been using (from Best Belts) is no longer on the IPF approved list. My purchasing experience with Inner Strength Products was excellent: the website is easy to navigate, shipping is reasonably priced, and the item arrived quickly and without too much wasteful packaging. I do not particularly like this belt - it is too wide for my frame, so it hurts my lower ribs and the top of my pelvis to wear, and leaves bruises along the upper and lower edge of where the belt was. I have trouble getting it adequately tight, as it is quite stiff. I know that this will improve with my breaking it in, but the discomfort it causes to wear makes this a daunting task. Also, it is very hard to take off. The belt is a good quality product, although I am not clear on why one would purchase a 13mm belt over a 10mm. That was my mistake. And I wish Inzer made 3” belts!
