Excellent flannel sheets that don't wrinkle and easily accommodate a thick mattress.  I bought two sets and will definitely buy more.  These are so good in every way that I threw out my old, normal sheets.

Comfort - 10 out of 10
Anti Wrinkle - 10 out of 10
Size and Fit - 10 out of 10 (No need to stretch that last corner to get the fitted sheet to fit.  Pillow cases easily accommodate large pillows.)
Perspiration - 10 out of 10 (Wick away moisture better than any sheets I've ever used)

I will never go back to normal sheets again.
