What Our Gearhead(R) Experts Are Saying:"I wore the Stanfield WP Extreme Cold Weather Mid Length Sock ice fishing on a bitterly cold day and my feet stayed warm and completely dry for hours standing on ice. The terry-loop interior made a real difference trapping heat when temperatures really dropped."Sub-zero pursuits leave no room for cold, wet feet, and the Stanfield WP Extreme Cold Weather Mid Length Sock is engineered for exactly that kind of demanding cold. An Aquasealz(TM) waterproof membrane blocks water from getting in while still releasing internal heat and moisture, keeping feet dry through deep snow, wading rivers, or standing on ice for hours. A terry-loop knit interior of merino wool and acrylic traps warmth in micro air pockets, while a seamless construction with elastic ankle support keeps the fit close and comfortable through long days in extreme conditions.
