Heavy cuffs
Color: Beige, Size: 38W x 30L
Runs a little small. Cuffs are heavy so had them removed. Like the look!

Inseam is way off.
Color: Burgundy, Size: 38W x 30L
They are nice, the waist is the right size, but the length is more for an orangutan. I’ll be lopping off 5 inches easy, not even close to a 30” inseam. Inseam inseam inseam.

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.
