Castelli - Women's Pro Issue Sleeveless Base Layer


Please use the ENQUIRY FORM/BUTTON for product details, color variants, and the latest stock information.

    This is the piece our pros requested for those in-between conditions where the Flanders is too warm and the Core Mesh is too cool, like Spain in February or Belgium in April. You're not looking for warmth from your base layer, just something to move the moisture away from your body and help your race jersey perform. Our 3D mesh fabric creates dead air space next to your skin, while the polyester capillary action moves sweat away.


    • Ideal for cool conditions when you need an extra layer under your jersey
    • 100% polyester 3D mesh fabric
    • Reduced seaming at shoulders for extra comfort
    • Double layer construction at neck
