For fit context comments, my husband is 5'7" / 143# / 32-33 waist and these bottoms in size M are a just right fit for him for roomy comfort for sleeping without being too big. They launder well for cold water wash and low dryer tumble dry and after several washes had minimal shrinkage but for a little in length - which benefit him with short legs. He likes the button fly. Also just right weight for Spring and Summer snoozing, he says. I thought the stripe he chose might look like a circus tent but paired with the Nautica short sleeve sleep tee in the sort of denim blue they are nifty.
