Deep Winter Wool Socks

Deep Winter Wool Socks are the warmest socks PNS makes — a merino-wool winter knit with arch support, reinforced heel and toe, and a compression fit for the coldest rides of the year. Where the Mechanism Thermal Socks handle everyday winter duty, this is the deep-winter grade: the pair you reach for when the thermal socks are not enough and the ride is happening anyway.
