There seems to be quiet a choice of JOAT bamboo socks. I'd prefer the thickest socks I could buy..
I wonder how these would compare for thickness with say Explorer wool blend socks..?

I have been caught out before with so called 'work socks' that would be only suitable for office work!
ps; Don't be offended by the first line of this message..I have been known to wear pink work safety shirts for 'Women Breast Cancer Awareness'.....
