My son is thrilled with his new bedding.  He has always slept with a down duvet, but he prefers this comforter because he no longer overheats while sleeping.  The comforter is fairly lightweight and might require an extra blanket for warmth.  The comforter has a dark gray solid on the reverse side.  This is made of polyester which has a slight sheen to the fabric and isn't as soft as cotton.  Being polyester should make it wash well, so it is perfect for my teenage son!
