Farm to Feet Denali Extra Heavy Weight Mountaineering Socks 9748 Wooly Blue

Very soft,warm enough and perfect for cold days.I wish they had other colors.

Won’t find a better merino sock or higher %

These are my warmest, softest merino wool socks I own. Farm to Feet is my favorite merino wool sock maker. These Denali socks are the highest % of merino wool that I’ve found anywhere at 91%. This is my 2nd pair, the 1st pair I got last season. One difference is the top of the sock is a different pattern now... no more diamond pattern-which is no prob. If you like thick socks, you won’t be disappointed. (I tried buying the DT flagship t4033 $30sock thinking it would be an extra thick heavyweight sock like it said, but it was only mid weight thickness) So this Denali is much better.
