I own about fifteen pair or more of 514 Levis so I know what the differences are. These welder jeans are tighter then normal 514's and the rear pocket flaps are not for me, just be sure you like that look, I don't. One pair was part polyester and a bit shinny, I really don't like those. You really must try jeans on before you by, 514's are made all over the world and every country has a slightly different cut. If you buy cheap jeans like these quality control is what you sacrifice but they are still my favorite and I wear them everyday.
