Well-made, very comfortable indoor pants. Yes they can be worn sleeping, but also for lounging around then house.  They are soft cotton, and very comfy.  Mine didn't drink much, and the large, thick tie really works as a belt.  The button fly is big and the fly off-set well, so no embarrassing exposure should happen!  I have worn them outside in a pinch, in the garage, backyard, etc., etc.  The pockets are nice and deep, and seem sturdier than other like-pants I own.  Of course, if you put your iPhone 8+ in the pocket, they might come down at the wrong moment!
