Patagonia Heavyweight Merlino Wool Blend Knee Socks

Conquer freezing temperatures and long days on your feet with the Patagonia Heavyweight Merino Wool-Blend Knee Socks. Engineered specifically for sub-zero outings, winter fly fishing inside waders, heavy-duty work, and cold-weather hiking, these knee-high socks deliver high-pile cushioning and reliable thermal insulation from toe to calf.

Crafted with Responsible Wool Standard (RWS) certified merino wool blended with durable nylon and spandex, they offer itch-free comfort, natural moisture-wicking power, and exceptional shape retention. The extended knee-high length provides crucial lower-leg warmth and prevents friction from tall boots, while the comfortable elastic cuff keeps them securely in place without binding or pinching.
