I am used to 400 thread count sheets & was a bit dubious about these 300 ct. While much thinner, there's a silky smoothness to them that makes up for it. That being said, the smoothness is not sateen which I do not care for. The smoothness is in the feel of the sheets & pillowcases. This is definitely a plus for those of us who live in the both dry & humid Southwest. These sheets are definite plus in the summer mos. which amount to 6mos.+ out of the year.
