OK, Gary. $70 for that large of a piece of material is a bargain from Smart Wool.
Now pay the $15-17 for a pair of sox (about 10% the size of a shirt) and you feet will love you forever--and I'm talking winter, summer in Texas..................
I've been wearing them for years and years--hell, I was married when I started wearing them and that was in the dark ages and I still have some of those socks. Now I'll have bad memories every time I put on a pair of the older socks.
