I got this set for my 14 year old. He is always hot when he sleeps, and absolutely loves this blanket and pillow set! It's 100% cotton. The blanket is breathable and not as thick as a normal comforter, but still keeps him nice and cozy if he gets cold. The pillow sham is made out of the same exact material, so it is thicker and more soft than normal pillow cases. It has a nice, light and classy pattern on it.
