Description Every climb worth making has a few switchbacks in it. When the pace picks up, the Switchback Mid Crew is the sock that keeps up.Our Merino Wool socks were born from the demands of our founders and ranchers- folks who spend their days pushing mile after mile as they steward 10,000 sheep across the rugged, high-elevation Montana backcountry. The ground they cover is steep and unforgiving; and their feet don't get a break until the job is done.The lighter knit of the Switchback Mid Crew breathes well, wicks sweat, and dries fast. Naturally anti-microbial Merino keeps your feet happy no matter the mileage. Light cushioning softens every step without the bulk that beats down your feet on a long push. Mid Crew height is right at home under a pair of trail runners or low cut boots.What holds up on a Montana ranch will hold up wherever your day takes you- the trail, the job site, or the ranch of your own. Forged with American Merino Wool that's grown, spun, and knit all in the USA.
