Castelli advertises it as its lightest jersey ever, the Insider 2 is a short-sleeved model ideal for indoor training and very hot summer days. It is made with a 3D mesh that wicks away moisture and dries very quickly, ensuring optimal comfort even during the most intense sessions. HEIQ Fresh Tech treatment provides odour control, and the semi-open mesh allows for maximum ventilation.
