Sturdy, thick, but very soon turning soft fabric, Seven well-spaced belt loops - your belt will NEVER separate like it happens in five-loop pants, nor will the tip of the belt stick to the side!
I am size 48 :( - they felt small to the size for the first ten minutes (without a belt), then were on a tighter side for an evening; after two days of mostly sitting in them - I do not feel them to the point that I think what would have happened if I ordered one size smaller :)
Wife liked the look so much, that I am ordering the second pair in a different color.
