Patagonia Lightweight Endurance Quarter Socks

These aren't around-the-block socks. They're made for miles of abusive terrain, with an over-the-ankle fit to frustrate brush and briar. Thin and lightweight, they feature a felted merino wool channel-knit construction for maximum cushioning with the least bulk. An open knit over the top of the foot increases breathability; the seamless Lintoe(R) construction provides chafe-free toe comfort. Made from 40% chlorine-free merino wool, 25% Coolmax(R) polyester, 20% nylon, 12% polyester, 3% spandex. Sock height is 5.5". Formfitting.
