Medio Long Sleeve Base Layer

Castelli Medio Long Sleeve Base Layer

Enhance comfort on every cool-weather ride with the Castelli Medio Long Sleeve Base Layer, the ultimate mid-weight cycling base layer engineered for chilly and unpredictable conditions. Its medium insulation wraps you in just the right warmth when temperature hovers in single digits, but efficient moisture-management technology wicks sweat fast to keep your core dry and your tempo high. Made from a soft, polyester stretch fabric, it fits like a second skin, letting you slip easily under your favourite winter jersey without bulk or bunching.

Beyond comfort, this crew-neck essential ticks every performance box serious cyclists seek: moderate, breathable insulation for steady pacing on long climbs; excellent sweat dispersal that banishes post-effort chills; and a versatile long-sleeve cut that pairs perfectly with gilets or full jackets.
