A means for holding up the trousers, belt loops were first added to the waistband of the Levi’s 501 jean in the 1920s when wearers began preferring belts over suspenders.
Jeans most commonly feature five belt loops, however, in the 40s Wrangler pioneered jeans designing by two additional belt loops for extra comfort while horseback riding.
To add strength to the construction, some jeans feature double layered belt loops with a smaller loop underneath the larger visible loop.
