Bandito 2 Merino 18 Sock

What Our Gearhead® Experts Are Saying:

"The Bandito 2 Merino 18 Sock is the sock I recommend when riders want merino warmth without giving up the precise shoe fit they rely on for performance. The thin construction is the key detail here, and it is genuinely impressive how much thermal benefit Castelli packed into a profile this slim. The 18cm cuff hits the right height for most cycling applications, and the merino blend handles moisture better than any synthetic cold-weather sock in this category."

Most cold-weather cycling socks solve the warmth problem by adding bulk, which creates pressure inside the shoe and throws off the fit that performance riders depend on. The Bandito 2 Merino 18 Sock from Castelli takes the opposite approach, building merino wool warmth into a thin construction that fits inside the shoe exactly like a summer sock does. The result is natural thermal regulation and moisture management without any of the compromises that usually come with winter hosiery.

The 18cm cuff delivers meaningful coverage up the lower leg while staying trim enough to work cleanly with any tights or leg warmers in your kit. For riders who refuse to let dropping temperatures change their shoe setup or affect their power transfer, the Bandito 2 Merino 18 Sock is the detail that makes the whole cold-weather system work without adjustment.
