>>2517435reached my hand in the gear bin for you. many different natural fibers have their own niches for /out/ uses. left to right here is merino sheep's wool, american bison down, and kashmir goat down. i got a bunch of stuff made from chinese yak down somewhere. and a pair of socks with qiviut in the blend.
just not the biggest on alpaca personally, merino isn't itchy to me.
