Whether it’s hot or cold, the natural crimp of the merino-wool fiber pockets lets the fabric regulate your temperature. 3x1 rib-knit legs keep socks from slipping down. Flat-knit toe seams. 72% merino wool, 27% nylon, 1% elastane. Made in USA. Women’s sizes:M(6 to 8-1/2), L(9 to 12). Colors: Mineral, Deep Sea.
