The Drytex Merino 7000 sock is designed to feet warm and dry, especially during low-intensity activity. The extra-soft 67% Merino wool blend is antimicrobial, wicks moisture, and provides excellent thermoregulation. Heavyweight cushioning was chosen for this sock for comfort and optimal warmth, especially for long days outdoors. The heel, toe and underside of the sock resist wear thanks to thoughtful reinforcement, and the cuff has extra stretch for fit and durability.
