I bought a fr canvas belt when it was the only one I could find (I'd gone away for a week and left my belts behind). It's durable but I find there's a bit of a sharp edge on the inside where the pressed metal is bent around to form the sides. If the trousers have a wide loop spacing I find the belt rides up over the top of the trousers and digs in. A weird issue I have with it I know and probably not once noticed by others. It's why I prefer my plastic cam lock webbing belt with money security pocket.
