I've been looking for a long time for pajama bottoms that aren't sweatpants (or at least are loose enough not to hug my calves). You are not. They are very loose around the waist and hips and then tight around the calves. They seem comfortable, light and soft for those who want this style! Warning: I'm usually a 31 waist and the average size was very loose (but I prefer them to be "comfortable" loose for sleeping).
