I bought a couple of ratchet belts about 3 years ago when I was looking for a belt that would withstand the pressure of a traditional buckle. Then I realized that the problem wasn't in the material, but in the style of the belt and buckle. One of my straps was finally starting to wear out so I found these straps to replace my existing ratchet buckles and I fell in love with my strap again. By the way, the trick to releasing is to release the pressure BEFORE pushing the button away from your body.
