Re: best jeans you can buy?? usa made
If you can get away from denim, check out the jeans and work pants from Duluth trading - the ones made from fire hose material. They are guaranteed forever!!!!! If you wear them out, tear/rip them, they shrink to much or you grow to much, they replace them free of charge. You just gotta pay to ship them back. They pay shipping to return them to you. Buy yourself 3-4 pairs and they are good forever. I've used their warranty on the fire hose pants and shorts and they stand behind them, no B.S., no hassle. They just replace with new.
They are not however made in U.S.A unfortunately.
On the pants I've learned to order 1 size up in waist and length. Once you wash them a couple times they shrink down just a bit and fit. They wear like iron.
