As a long time lover of 100 % Cotton, in her many glorious forms, these thick, beautifully crafted sheets that allow my skin to breathe in harmony are a luxury I consider a necessity. I bought very similar ones, forget the name of course, over 10 years ago from Great Offer Stock, and they wore well all that time. Yes I alternated and used other very fine quality cotton sheets during that time, however those similar to these are the best!
