User Review: Therm-a-Rest Compressible Pillow
I like this pillow....although mine seems to have noticeably less filler than my wife's (who got hers a few months before me)...whether I just got an anomaly I don't know, but it still keeps my head nice and padded and warm. I got the small size, fits in my mummy-bag head area (?) nicely. Mine seems to compress more over the night, I wish I had hers.
