The CASTELLI Prologo 7 long sleeve jersey is a lightweight, breathable jersey that allows you to train at a good intensity in total comfort. The long sleeves provide extra protection from the sun or a cool morning or autumn day, without weighing you down. The jersey has a modern cut that ensures an optimal fit in the cycling position. The cut of the back panel, for example, is noticeable, as it falls well to the lower back. The hem has a siliconised support band. The Prologo 7 jersey uses a micro-piqué polyester fabric on the body to ensure excellent moisture and body temperature management. The sleeves are made of Velocity Rev2 fabric to optimise aerodynamics. A silicone band around the hips ensures a perfect fit. Finally, the model blocks 97% of UV rays so you can enjoy your ride without worrying about sunburn. The full zip is practical and the three rear pockets are useful for keeping your essentials for training. A jersey that incorporates many of the brand's technologies to give you great versatility.
