The Heavyweight Merino Endurance Knee Sock is tailored for the most serious adventurers, providing comfort in the world's most extreme environments. It employs Merino Performance Fusion Technology to deliver durable padding, well-balanced insulation, efficient moisture-wicking, and exceptional durability for comfort throughout the day.
The Performance Fit offers a close and supportive fit that won't slip down or bunch up in your footwear, no matter how long your adventure lasts. The toe box is sealed with an insulated Flat Toe Seam to eliminate cold spots, and the sock stays securely in place thanks to an Elasticated Arch and a 3D-shaped heel cup. Constructed with Lycra and set using our Thermo Fit process, this sock bounces back to its original shape and size after every wash.
