These pants are incredibly durable, they last 3x-4x as long as heavy duty blue jeans in a tool shop where I'm leaning on machines covered in sharp metal chips and grease and grinding dust. They take a while to break in fully and get soft but they are not really supposed to be sleep wear or sweatpants anyway. They have become my primary pants after a 8 years of destroying every pair of jeans I bought and my first pair is still going strong after 1.5 years.
