Due to unevenly distributed and weighted equipment carried on the side or the front of duty belt assemblies, wearers often complain of back aches and pain and postural problems. The rigidity of the belt adds to the issue when wearers have to maintain various upright, sitting, squatting and bent over positions. An Described is an ergonomic duty belt assembly comprising: a longitudinally and laterally flexible inner belt having an exterior face provided with a hook and loop fabric; a longitudinally and laterally flexible supporting belt adapted to be affixed over said inner belt having an interior face provided with mating hook and loop fabric; a base material of each of said inner belt, said supporting belt, said hook and loop fabric and said mating hook and loop fabric being woven with a material having elasticity properties, thus providing longitudinal and lateral flexibility of said duty belt assembly; said supporting belt further comprising at least one polymer insert affixed between the base material layer and the hook and loop fabric of the supporting belt, wherein the polymer insert is not stretchable longitudinally although it may be somewhat flexible; and said outer belt being removably mountable to said inner belt, said hook and loop fabric on said inner belt being adapted to be affixed to said mating hook and loop fabric of said supporting belt.
