The Explorer Heavyweight Boot Sock is one of the warmest options from Bridgedale. It's meant for expeditions in cold environments. Bridgedale built it out of a merino wool blend for balanced insulation, moisture management, and outstanding durability. It has a supportive fit that won't slip down or bunch when you're halfway up the mountain.
