I have tried several pairs of double-front work jeans from the Working Person's Store, and all have been satisfactory. I had never heard of Key Jeans before I saw this website, and the price isn't bad, so I thought I would try them. They seemed really huge at first, and I washed them in hot water. Then they fit pretty well. They're still fairly stiff after several washings, but comfortable nonetheless. If you want some really heavy duty work jeans at a good price, I don't think you'll be disappointed with these.
I'm not giving them five stars only because the waist has continued to tighten up a bit as they've been washed.
