From summiting Everest to winter extremes, Heavy Expeditions are what this boot-length sock was made for. Our thickest sock places fine gauge merino wool on the inside of more durable outer layer, completely enveloping the 'custom-fit-feel' of our patented knitting structures, This keeps you warmer and drier where you need it in the most extreme conditions. Don't mess around. Off road all the way.
