This is the third time I have purchased this brand/style of sock from Amazon, and this time the socks are much more sheer than before.  I saved the old packaging and the previous wool content was 54% the socks just delivered are 56% wool.  The real change is the thickness of the product. The new product is much more sheer.  Don't know If I will keep them or not,.  The description of these socks on the web site shows the old fabric content. After using the socks and washing them, I am pleased with them.  They are somewhat different, but not substantially. I'll buy more.
