Castelli Women's Pro Issue 2 Base Layer

You could be forgiven for thinking this is a standard string vest, but the Women's Pro Issue 2 Base Layer goes far beyond that. It makes use of an advanced 3D mesh to enhance moisture control and deliver sweat-free cycling comfort. The 3D structure works brilliantly thanks to an increased surface area with which to draw excess sweat away from the skin. The semi-open design also allows for excellent ventilation and with greater airflow, it enhances sweat evaporation to keep you cooler. The result is a base layer that will leave you feeling drier and fresher as temperatures rise.
