The Castelli Pro Issue Baselayer (White) is a high-performance sleeveless cycling baselayer developed for riders who demand exceptional comfort, efficient moisture control, and optimal temperature regulation in every riding condition. Designed using Castelli's extensive experience in professional cycling apparel, this technical baselayer acts as the essential first layer between your skin and cycling jersey, helping you stay dry, cool, and comfortable from the first kilometer to the last.
Whether you're climbing alpine passes, racing in hot summer conditions, training indoors, or enjoying long endurance rides, the Pro Issue Baselayer works continuously to move perspiration away from your body, allowing your outer jersey to evaporate moisture more efficiently. The result is a more stable body temperature, reduced discomfort, and improved riding performance.
With its clean White finish, lightweight construction, and race-inspired fit, the Castelli Pro Issue Baselayer is an indispensable addition to every cyclist's wardrobe.
Castelli has built its reputation by developing performance apparel trusted by WorldTour teams and elite cyclists worldwide. Every product reflects decades of innovation, premium materials, and rider-focused engineering.
The Pro Issue Baselayer continues this tradition by combining advanced moisture management, lightweight comfort, ergonomic construction, and premium Italian craftsmanship into one essential performance garment.
Designed to disappear beneath your jersey while enhancing every aspect of your ride, it provides the technical foundation serious cyclists depend on.
