Love the Glacier!  I would recommend a pillowcase geared towards cooling though— not because it’s not cool to the touch but just because the material the outer cover is made of makes it constantly try to slide out from under my head. ( side sleeper ). I ordered some LUXE cooling pillow cases and it’s my favorite pillow to sleep with.  I got the 1.0 and it is plenty thick for me as a side sleeper.
