Excellent
"Use case: took this to a festival because once the sun hoes it gets very cold, nut you don't want to carry a coat or big blanket around all day in the heat. I have disabilities, so I'm often sitting on the viewing platform. Using it as a neck pillow during those times was suuuuper comfy. Or, it fit in my bag or clipped onto the outside. Once it got cold I took out the blanket, clipped it together as a cape, and I was plenty warm until bedtime. The only problems are: you obviously can either have a pillow or a blanket, not both (unless you stuff something else into the pillowcase), and it's tricky getting it back in the same way as when you first get it. I accidentally made it a bit lumpy."
