Good buy
Size: 28W x 34L, Color: Medium Indigo
My 16-y/o 6' grandson wears the 28"-34". Not easy to find. These fit him well. Material is regular blue jean. Good value

Nice jeans, but too tight in the thighs
Size: 31W x 28L, Color: Light Wash
I liked these jeans overall — good quality and the stretch feels nice — but they were a little too tight in the thighs for me. If you’ve got more athletic legs, you might want to size up or try a different fit.

Same sizes but different fits
Color: Light Green-new, Size: 32W x 32L
Great color and good fit. Feels more like a Jean. I bought two pair-exact same size. 32w x 32 length. Light green was exactly what I wanted. The maroon red was more like a jegging than jeans. Not what I wanted. Supposedly same style - so just be aware fits were completely different!
