I have ordered three sets of sheets from Wayfair so far and all have been lovely.  This set is the thinnest material but it appears to be strong and good quality.  After washing they were very soft and not as wrinkled as heavier sheets.  They are not crisp like percale however.  I think they are great for a summer sheet when you don't want a heavy material over  you.  Will continue buying the 800 thread count for winter use.  

Pros: Good price, soft, smooth
