Bison down/yak/Primaloft yarn- The "Scottie" beanie/toque/watch cap
This one uses the same yarn as the foot of our "Mil Top" socks.
"Scottie" is the guy who created it; one heck of a headwear designer - Scott Baker. And as frugal a buy as any Scotsman could want!
40% American Bison Down, 40% Tibetan Yak and 20% Primaloft (siliconized polyester). Slightly more grey and less brown than our other hats (the yak is almost black and blends well with the bison.
It is a bit of a looser knit, but plenty warm, with a 2" extension that can be left flat or pulled up as a second layer over the ears .
Soft and light; warm, but not stifling. Put it on and forget the chill. It also does not restrict hearing as much as some of the others, which makes it a great hunting beanie - soft (and thus quiet) and unrestrictive.
