These are made of 100 percent cotton canvas. They are rough, tough and heavy. It is hard to think of a more durable pant that still gives you reasonable mobility. The fabric does get wrinkled very easily but for most activities you use these for, who really cares?
I am usually a 32 Waist/32 Length but these 32W/32L were so long that I had to roll them up. I didn't want to try the next size down because the waist was a bit too tight and I was worried they might shrink into floods. With thin soled sandals on I have to roll them up but with thicker soled shoes or especially boots they fit fine.
The pockets have wide angle cut openings to fit your hands and wrists in easily.
These are more of a Carhartt style khaki than a casual Friday khaki. But they look at home in town. They don't look like you just got off the job site.
Fairly expensive but worth it for the durability and style if you work and play hard a lot in rugged environments and appreciate a good looking pair of pants.
