I wear this belt with blue jeans and also with my uniform pants. More recently I've worn it over my reflective safety vest while bicycling. This belt easily and comfortably supports my 8 1/2 " X 5" tool bag, smart phone, large pepper spray and battery pack for my helmet mounted headlight. I've noticed that when I wear it at work I usually have to tighten it 2 or 3 times per shift. My job is pretty physical and I do sweat a lot so I don't blame this on the belt. Or maybe the belt is somehow stretching, I don't know. It doesn't really matter because I love the belt and wouldn't wear anything else.
