Too Much Back, Ain’t Enough Slack
Color: Brown, Size: 36W x 30L
Sadly the color doesn’t quite match the photo—it looks cheaper IRL. However, the form of the pants are cool, but they don’t fit me.
TLDR: These pants aren’t for guys with back. Good looking style though.

Color was off. More plum than burgundy
Color: Burgundy, Size: 36W x 32L
The color was more plum than burgundy. I returned them. Not a plum pants kind of guy. I have gotten other colors. I actually love the fit.

Do not trust sizing or measuents
Color: Black, Size: 32W x 30L
Sizing way off. Can barely fit on and no where close to buttoning. Same pant measurements in another pant bought at the same time no problem. Sizing and measurements off.
