A longtime favorite for outdoorsmen with an updated 47% merino wool, 27% olefin, 20% stretch nylon and 6% Lycra fabric blend for superior moisture-wicking performance and warmth. Merino wool and olefin (a moisture-managing fiber) band together to transport perspiration from inside the sock to the surface where it evaporates quickly. The finer-grade Australian merino wool has long, supple fibers that dont irritate skin. The ankle- and foot-hugger designs make for a better fit that stays put throughout the day. Per pair.
