I filtered for Egyptian Cotton sheets. These are NOT COTTON. The print on the label has been adjusted to read "with the soft touch of Egyptian cotton". The fine print says they're actually made from "high strength mirco (sic) fibre yarns." None of the labels on any of the pieces gives a fibre content.  Caveat emptor.  I was suspicious of that from the price.  They're supposed to be turquoise, but they're just pale blue.  I like that there are 4 pillows, and I'll live with the colour since I need the sheets for the new bed just delivered.  We'll see if they're as comfortable and cool as cotton in our hot summers.  Who knows. Maybe I'll love 'mirco fibre' sheets as much as cotton?
