I have 8 boys and the best luck I have had in purchasing jeans has been Levis through Amazon.  Levis are one brand that I can pass from one son to another.  They don't wear out quickly.  They fit exactly as their description.  These were a straight cut and with the adjustable waist band, they fit perfectly.  They fade, but not too quickly.  I washed these with similar colored clothes the first time and after that, did not worry.  The color does not keep washing out to affect the other laundry.
