I like the silk material of the case. I wanted to try the thinner pillow to see if the thickness might be irritating a groin pull - I can’t say for sure yet but the pull seems a bit better. My only negative comment is that when you remove part of the pillow along the cut you end up with a flat surface rather than the normal curve that nestles your leg and helps guide it into the proper position. Not a big deal, I just need to be more conscious.
