I was reluctant to get flannel sheets for fear that they would be too hot. But my wife convinced me and I'm glad she did. These sheets are: 1) perfect for cold weather - they don't have that chill-factor when you first climb into bed and they warm up in an instant 2) super comfortable - they don't get too hot and they are very soft 3) definitely deep-pocket - other sheets that claim to be deep pocket...but these could clear 20inches easy. our mattress and topper is about 15 inches, so those sheets have plenty of room...no sheet clamps needed! Would definitely buy again!
