These sheets are the best fitting product I've found.  They are so comfortable and soft that both my husband and I believe that they are superior to any other flannel sheets purchased.  I live in MA and it's been a cold winter so far. 
It's so nice when we slip into bed the sheets are warm and comforting.  I will purchase another set so when I change the bedding, I'll have a fresh pair to use.  
I would highly recommend them to anyone who lives in a cold climate!
