Anyone who's spent a waterfowling trip standing and setting out decoys in near freezing water knows how fast ice-cold temperatures can sap your body of heat and ruin an otherwise great outing. With their 23" length and incredibly dense loop-knit construction, our Knee-to-Toe Socks surround your entire lower leg in a blanket of warm, cushioned comfort. And the spandex-enhanced rib-knit neck fits perfectly underneath waders or hip boots without bunching up at the knee or ankle. They're made of 68% Merino lamb's wool/24% stretch nylon/7% polyester Thermolite/1% spandex. Made in USA. Wall thickness: 7.5 mm. Sizes: M(6-9), L(9-12), XL(12-15). Color: Gray.
