I was so disappointed when these sheets arrived. They are NOT SOFT at all, and you can see through them. I guess that is the ProAir part but am not impressed. I wanted to exchange them but found out there is no return or exchange on sheets. For them to be so expensive that was a real disappointment especially since I ordered 2 sets. The last sheets I bought from Tempur-Pedic were so nice that I literally worn them out. Buyer beware!!!
