These arrived during the summer in Las Vegas. Washed them and put them on, and I hated them because they felt so hot to sleep on. I thought they felt like a really cheap flannel. (BTW, this drove me to buy 500+ thread count sheets here which I loved and based upon which I resolved never to go below 500 again.) So I washed these and put them away. I put them on again in the winter and now I love them. They are warm to sleep on, and they are so soft they do almost feel like a very light flannel. I may buy another set for the guest bedroom if someone visits during the winter.
