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!

Good product with quality-control issues
Color: Dark Grey, Size: 31W x 31L
I really like these jeans. I own them in almost every color they offer, but the manufacturing consistency is hit or miss. The latest pair I bought has a much smaller pocket opening than the others.
I also always order the same size (31×31), but when I got the red pair they were ridiculously long, more like a 31×36.
And the first khaki pair I bought had pockets about half as deep as the rest. My iPhone would literally stick out of them.
That said, for the price and overall look, they’re still a solid buy.
