The name Prologo means in Italian "Prologue", the opening salvo of the Grand Tour. However, many of our customers pronounce it as "Pro Logo". And we don't mind. Prologo jersey is now in its sixth generation equipped with new material, cut and design. The fabric used is remarkably subtle but still resistant and contains polymer-associated bioceramic nanoparticles that reflect long infrared light to protect you from the hot sun and help maintain your own body temperature. The construction also borrows many of the racing jerseys. The design helps the jersey sit perfectly on the waist with large pockets on the back. Side panels that vent the back without letting a lot of air from the front and also the YKK® Vislon® sliding zipper.
