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.

  • Responsible Wool Standard (RWS) Certified: Made with ethically sourced merino wool that supports better animal welfare and sustainable land management.

  • Heavyweight Thermal Performance: Dense, plush cushioning traps heat to keep feet and calves warm in freezing conditions and ice-cold water.

  • Durable & Stretch-Fit: Nylon and spandex blend enhances durability in high-wear areas while providing long-lasting stretch and recovery.

  • Over-the-Calf Protection: Knee-high design provides full lower-leg coverage, ideal for pairing with wading boots, work boots, or ski boots.

  • Moisture-Wicking & Breathable: Naturally odor-resistant merino wool pulls moisture away from skin to keep feet dry and comfortable all day.

  • Activity: Winter Wading / Fishing, Hiking, Work, Cold-Weather Outdoor Wear

  • Material Blend: RWS-Certified Merino Wool, Nylon, Spandex

  • Height: Knee-High (Over-the-Calf)

  • Cushioning: Heavyweight / High Cushion
