These sheets are RIDICULOUSLY warm. I admit that I am totally late to the game, but when I finally started researching sheets (what a silly subject to "research,") I found that flannel sheets might solve some of our problems, because my husband is a sheet SNOB. He will only sleep on sheets he deems "soft enough," even though he has no measurable definition of "soft," leading to some sheet purchases that left only one of us satisfied (me: I liked the pattern). I get really, really, really cold at night. My husband does not. Because of this, my mother-in-law bought me a twin sized electric blanket for our bed, but that helped only when I remembered to turn it on before we went to bed, otherwise I was settling into a frigid sheet set, and eventually warming up. Enter the flannel sheets. They are not biting cold when I slip into them, even if I forget my electric blanket, and now, I don't need to sleep with the electric blanket on all night. Now I turn it on during my bedtime routine if the night is particularly frigid, and turn it off when I settle in to bed. Long story short, my husband was satisfied with the softness, and I was happy with the warmth, and everyone won. I am considering buying a second set this year so that we can change our sheets instead of wearing them down with frequent washing.
