The Castelli Prologo 7 LS is a men's long-sleeved cycling jersey, perfect for chilly rides in spring and autumn. You can also wear this light cycling jersey on summer days, when you want to protect yourself against the sun. This is one of the most important properties of the Prologo 7 LS. The Castelli Prologo 7 LS body consists of feather-light Micro-Piqué polyester. This material ensures good ventilation and it also offers excellent protection against harmful UV rays (UPF factor 50). The long sleeves are extremely light and stretchy. As a result, they do not feel too heavy, but still block 97% of all UV rays (UPF factor 30). The front of the Castelli Prologo 7 LS has a YKK Vislon zip with neck guard. It is a full-lenght zipper, so it is easy to put on and take off. The three back pockets are extended, so they sit at the perfect height. The waist has an elastic silicone gripper, which prevents the jersey from creeping up. Finally, there are reflecting details on the pockets. These make you more visible circumstances where there is little light. Do you want to be comfortable during crisp spring and autumn rides or good protection from the sun in summer? The Castelli Prologo 7 LS will help you in both cases.
