Castelli Logo 18 Merino Sock

What Our Gearhead® Experts Are Saying:

"The Castelli Logo 18 Merino Sock is my go-to recommendation when riders want cool-weather performance without giving up the precise fit they count on in warmer months. The thin merino construction is genuinely impressive, and the 18cm cuff integrates perfectly with any tights or leg warmer setup. The two-tone colorblock design is one of the sharper-looking options in the category and holds up well after repeated washing."

The Castelli Logo 18 Merino Sock brings the same thin, performance-focused construction as Castelli's other merino offerings but adds a high-contrast two-tone colorway that stands out in the peloton. The merino wool blend delivers natural warmth and moisture regulation in a profile slim enough to preserve the precise shoe fit that matters to performance riders. Nothing about the fit changes when the temperature drops.

The 18cm cuff sits at the right height to integrate cleanly with leg warmers or bib tights without overlap issues, and the merino construction handles the transition between efforts and recovery better than synthetics in the same temperature range. For riders who want their cold-weather kit to look as deliberate as it performs, the Castelli Logo 18 Merino Sock delivers on both counts.
