These are thin but not sheer and cool to the touch. They have quite a bit of stretch and bounce back so you don’t wake up in enormous frumpy pjs. Only complaint is that the wide leg + stretch means the legs bunch up in bed, unlike heavier cotton or silk or a long john style that tapers at the ankle. I wake up with them bunched up to my knees which is pretty annoying.

These are so cute and soft. I’m surprised other reviewers haven’t mentioned the weird sizing though. My hips are wide so I always need a size up in bottoms and pajama tops tend to be too big. But I got an xs in these and the bottoms were great while the top was touch small.
