The word "Prologo" in Italian means "prologue": the beginning of a Grand Tour race. But many of our customers pronounce it "Pro Logo", and we don't mind at all.The Castelli Prologo jersey, in its sixth generation, has a big logo, but more importantly, it brings you technology straight from our experience with professional riders. The fabric is remarkably soft and stretchy, and it has bioceramic nanoparticles added to the fused polymer, which reflect infrared light to both protect you from the blazing sun or help your body retain heat. The construction also borrows a lot of elements from pro racing: the same back panel construction that helps the jersey stay snug around the waist, while leaving room for large pockets placed lower in the back, wraparound side panels, allowing for back ventilation without letting too much air through from the front, and an easy on/off YKK® Vislon® zip.

  • New lightweight and breathable Punto fabric.
  • Horizontal stretch for a perfect fit, with limited vertical stretch for good pocket support.
  • YKK® Vislon® covered zip.
  • Sublimated Castelli logo overlay on a dyed fabric base.
  • Back panel with 3 pockets and silicone waistband on the inside back.
  • Reflective piping.
