I'm a country boy and an electrician, I'm tough on jeans. I gave these a try after years of having Carhartt loggers jeans only last 3-6 months before they tore in the crotch, thigh, or ass. When I got the first pair of these they felt much thicker, better stitching and are cut to hug the waist a little tighter. I actually think the tighter waist helps them hold up. I climb, kneel, squat and stoop regularly. When your jeans fall down around around your ass it puts more pressure on the areas where the Carhartts failed. These jeans seem to be holding up well after a few months.
The reason for 3 stars is because when I ordered a second pair they were missing the left utility pocket. This is no good since that is where I typically keep my phone (it doesn't fit in the right one). Also, I collected a baseball size wad of thread from nearly every seam. I probably should've sent them back.  Still a good jean, just wish they were more consistent.
