Noticeable warmth after 30 minutes.
At first I was amazed by the mash look through the packaging, but after unpacking it for the first time you could see that the important back regions were additionally designed with the ceramic padding. After the first 30 minutes of use you can feel them clearly. In my opinion, an XFull size also fits a wider bottom.
