The ultimate knee length sock for keeping the elements at bay

Our iconic waterproof sock at a length that will keep you dry and on the move. We designed the Waterproof Cold Weather Knee Length Socks to keep you dry, warm, and protected through frigid stream crossings, rainy hikes, chilly commutes, wet and cold hunts, and even working outside in cold and wet weather.

Wet and cold feet are definitely no fun and can lead to all sorts of not-so-good things outdoors, including numbness, blisters, and frostbite. These socks will keep you warm and dry in rain, snow, and mud while the knee length will give you that added extra bit of protection. The ultimate sock for making the elements a non-issue.
