Review on 👕 Carter's Boys' 2 Piece Fleece Set 347g178 by Aaron Schultz

I checked this specifically because I know some pajama tops and bottoms are not fleece. When choosing a raccoon, 100% polyester is written, in the version with a raccoon not at all. The top is NOT fleece. My son said he was cold from above. I never understood the importance of different upper and lower materials. Do you only freeze half of your body?!? If you use a heavier blanket to keep your upper body from getting cold, then your lower half will sweat. I just do not understand. Very frustrating. Also frustrating when the description lies.
