Had taken one along several years ago, doing winter "Alpine Roving" in Germany and Austria. Fantastic "Egg Warmer!" Can be worn under another hat (Like alpine foresters used!) and even under a knit topper like a watch-cap or a French "Vouyager" stocking-cap with pom-pom.
And it's also a capital "sleeping-cap" for winter bed-time wear!
You know, I hope, that a warm head goes far toward making the rest of you feel warm; and toward that end, this cap's a great addition--- not as bulky or clumsy-feeling on a pillow as a watch-cap, nor does it seem as likely to throttle you in your sleep as a long stocking-cap.
It's just warm & comfy! (Posted on 7/30/15)
