Bought these since they were California King size with very deep pockets. I have a Cal King mattress now in the older water bed frame, so getting fitted sheets to work on it w/o pull loose is a chore. I usually just buy two flat sheets and skip the fitted one.

I haven't had  new flannel sheets for quite some time. Living in north Texas they aren't really needed. Most nights with these sheets and a cotton thermal blanket is enough, but are great w/ the down comforter.

I washed them per instructions the very 1st time, there is a lot of lint deposited on the catcher so I don't know just how that will affect the thickness over time.

They are very warm, soft but not fluffy soft. Being 100% cotton they do wrinkle, but after stretching them out on the bed they smooth out.

I'm sold on this brand and this like other things I have purchase through Wayfair have been an excellent choice.
