The Patagonia Heavyweight Merino Wool Blend Knee Socks are built for warmth, comfort, and durability in cold conditions.

Made from Responsible Wool Standard (RWS) certified wool, blended with nylon and spandex, these socks offer excellent stretch, recovery, and long-lasting performance while supporting better animal welfare and sustainable land management.

Designed for wading boots and extended outdoor use, the knee-length socks feature a form-fitting design, reinforced heel and toe for durability, and a soft terry-loop footbed that cushions and breathes for all-day comfort. Additional features include patterned stretch on the top of the foot, a mesh arch brace for snug support, and solution-dyed support fibers that reduce water use during production.

Made in the USA at a family-run factory, these socks combine sustainable materials, functional design, and superior comfort for anglers, hikers, and outdoor enthusiasts alike.
