I have been looking for regular percale sheets.  I miss the crisp cool feel so felt I was settling for these.   After washing ,these sheets came out of the dryer a wrinkled ball.  It was somewhat difficult to make the bed because of this.  However ,even though the wrinkles still have not fallen away the sheets are soft and do not slide around.  Also so far the fitted sheet has stayed tucked.  If wrinkles make you crazy these are not for you but otherwise so far so good.
