Stratus Plus fabric offers improved wicking and breathability to help you regulate your body temperature by actively moving moisture away from your skin. Mesh panels on the sides and at the lower back improves fit and also offers better cooling.
The Castelli Prologo 4 is fitted with three open rear pockets for all your ride essentials. Reflective tape gives you extra visibility on the roads.
