Made in the USA of a 60/30/10% wool/nylon/Lycra blend, the One Merino's reassuringly dense, providing a fair bit of both support and cushion. They're channeled along the top of the foot, the cuff is nice and snug, and they're soft. Mmm... S O F T. After 15 months' near-constant use (and probably improper sock-drawer balling technique), they feel like new. We've worn them during August snowstorms, monsoon season deluges, running and hiking (sacrilege, we know), and have never been disappointed.
For even short rides in 90 degree temperatures, the Swiftwick's Merino series are probably too much sock. For shorter rides in the 70's, too, we might still reach for lighter socks. That said, if we're headed out for any ride- on road or off- that has any possibility of becoming epic (ie: featuring rain, walking or the shedding of big man tears), the One Merinos are where it's at
