Wrangler AuthenticsMen's Classic 5-Pocket Relaxed Fit Flex Jean

As these jeans fit at natural waist, do they have a longer front and back rise e.g., 19”or20” Back x 16or17” Front for 44x30 size?

will these shrink in the dryer?

too long at 28" why not make 27 or 26 for us short fat guys, eh?

These all say "available in both 100% cotton or flex denim - choose a pair that best fits your needs". how do you tell which are which?
