Not a believer in Carhartt jean pants

It drives me nuts that the zipper doesn't stay up. I think they are okay jeans but when wearing them I have a constant habit of checking my fly which is annoying because I am not sure if the zipper is down or not. I also don't like how these are tapered down to the ankle where the jeans won't fit over the tongue of my sneakers. I have Carhartt pants that are not jeans and they are amazing, so I thought these jeans were a fluke, so I bought a pair of Carhartt carpenter jeans and again I have an issue with the zipper. So I no longer will be buying Carhartt jeans.
