In Forever Grey, the Patagonia Heavyweight Merino Wool Blend Knee Socks deliver understated style with high-performance warmth and durability. Available in sizes M through XL, these over-the-calf socks are built for cold-weather missions where comfort and coverage matter most. The thick merino wool blend offers excellent thermal regulation and resists odor even after extended wear, while recycled nylon adds strength for season after season of use. Strategic cushioning underfoot and along key pressure zones ensures all-day comfort whether you're wearing wading boots, ski shells, or winter hikers. Stretchy ribbing keeps the socks in place without digging into your calves. These are the socks you'll reach for when the temperature drops and the adventure doesn't slow down.
