Ya, I could have made it smaller, but since it's primarily for the John Muir Trail this summer, I will have some additional soft pieces to stuff inside.
It just may get kind of flat if it gets too cold at night.
Since it kind of cradles my neck, though, I don't wake up cold as often. Also, I'm not fishing my pillow (previously made out of a stuff sack or just clothes) out from wherever it decides to slide. This one really stays in place.
