I finally found one for myself, and it arrived just in time, as I was fighting a wicked cold. Even with my head throbbing and my nose running, I got to hang out like a Jedi all day.
It's truly like wearing a hug. Even the color is perfect: cocoa. And I've discovered some other benefits: if somebody stops by my place unexpectedly, I can be "just about to hop in the shower". And whenever I get the mail, my neighbors wonder if I'm a mental patient.
Get one, and join me.
